reminded himself then that most fellow travellers seen at airports, railway stations and boarding liners appeared unprepossessing until one got to know them; yet his impression was strengthened on the arrival of the couple who had been motoring through the night from Scotland. The man was very tall and so lean that his skin seemed stretched over the bones of his face to a degree that made it almost corpse like, while the woman had the most disconcerting squint that he ever remembered seeing.
In spite of the delay, which held up the take off until twenty minutes to eight, the flying conditions were so good that the aircraft made up most of the lost time, and they came down in the brilliant sunshine of Nice at ten past one. Molly and Malouet were both there to meet them and, after Beddows had been introduced, the elderly ex inspector said
`I regret to say I have no news for you; but one gets as good a lunch at the airport restaurant here as anywhere in Nice; so I have booked a table. While we eat I will tell you all that is known of the most extraordinary occurrence last night.’
The meal justified his recommendation, but John scarcely noticed the wonderful selection of hors d'oeuvres, or the point at which he passed from eating Loup flambe to Escalope de Veau Milanese he was too intent on Malouet's report and the discussion that followed.
Apparently getting Christina out of prison had proved a much easier matter for the Canon than her friends had supposed would be the case, as he had found it necessary to exert his occult powers on only one person.
Three nights before, a murder had occurred in Nice. At a bistrot in the old part of the town a sailor had been mortally wounded by a knife thrust during a brawl in which several men were concerned. There was some doubt which of two men had delivered the fatal stab, and the patron of the place declared that a girl called Marie Courcelle must know the truth, because the quarrel had been
over her and she had been within an arm's length of the victim when the stabbing took place. The two suspects were Marie's lover and her brother, and both were under arrest, but she, evidently reluctant to give evidence against either, had promptly disappeared. However, the police had picked her up the previous morning in Marseilles, taken her into custody as a material witness, brought her back to Nice in the afternoon and lodged her in the women's prison which, also held Christina.
In accordance with French police practice, the huge d'Instruction had ordered a re enactment of the affair at the scene of the crime with all the principal participants present; and that no time might be lost he had ordered it for that evening at approximately the same hour as the stabbing had taken place two evenings earlier. It was at this point that the Canon must have entered the game.
The assumption was that he had learnt of the affair when, on his arrival, he had discussed ways and means with the de Grasses and had decided to make use of the huge d'Instruction. In any case, for some reason which this examining magistrate was afterwards utterly unable to explain, he had written Christina's name instead of Marie's on the form authorizing the release of prisoners under guard for questioning. A Black Maria had picked up the two men then called for Christina. The head wardress or duty knew nothing of the enquiry the magistrate was conducting and had acted on the instruction to hand over Christina, simply assuming that she was required for questioning about her own case at the Prefecture.
On the arrival of the Black Maria at the bistrot the mistake had at once become apparent. The magistrate, still presumably under the influence of the Canon, had then decided that the Black Maria should remain outside for the time being with the two men in it, while Christina was sent back to prison in a taxi and Marie brought there instead. A single gendarme had, quite reasonably, been considered an adequate escort for one young woman, and as a taxi driver, who had been having a drink at the bistrot when it was temporarily cleared by the police, was still outside among the little crowd that had collected they set off in his cab.
In the light of what had then occurred it seemed certain that the taxi driver was one of de Grasse's people, and had been deliberately planted in the bistrot. After driving a few hundred yards he had turned into a dark alley way, pulled up and opened the door of his cab. He had told the gendarme that he had stopped only to slip into his lodgings to pick up the thermos of hot coffee his wife would have ready for him for his night's work. While he was talking, another man opened the other door of the cab and, as the gendarme turned, squirted a water pistol in his eyes. The driver had then hit him on the back of the head, rendering him unconscious: He had come round to find himself bound, gagged and face down among some bushes. Later he had recovered sufficiently to squirm his way on to a path near the gate of a private garden, and to attract the attention of a passer by. He had been dumped in the grounds of a villa on the road to Villefranche and he naturally had no idea what had become of the taxi or Christina.
When Malouet had finished his report, C. B. asked, `How about Upson's seaplane? Is it known where he landed the Canon?'
`We think so;' Malouet pulled at his grey moustache; `but we cannot be absolutely certain. Last night there was a strange occurrence out at the great reservoir from which Nice draws her water supply. It is situated some miles inland from the city, up a broad valley in which few people live, other than scattered market garden cultivators. Soon after dark a car drove up to the quarters of the Superintendent. The men who work there had gone for the day; so he was alone except for his wife and son and the night watchman, who has a small office in the building. Four armed men got out of the car, entered the place, herded its inmates into the boiler room and kept them there for three quarters of an hour. There was no attempt at robbery and no damage done, other than the disconnecting of the telephone.
`When the intruders had gone the Superintendent reported this apparently pointless hold up to the police. They could offer no theory to account for it then; but further enquiries in the neighborhood this morning elicited the information that a seaplane was seen to come down on the reservoir about an hour after sunset. It would not have been visible from any considerable distance, but several people saw it land, and take off again about twenty minutes later. A woman living nearby states that a covered lorry with powerful headlights had been stationary on the road alongside the reservoir for some time before the plane came down. Such a large sheet of water would, of course, be easy to pick up as long as there was any light at all; so the headlights near it were probably used not only to help guide it in, but also as a signal to the pilot that all preparations had been made for his landing. Evidently, too, the men who held up the Superintendent and night watchman did so to ensure that they should know nothing of this illegal proceeding until after it had been completed; so they would be unable to interfere or communicate with the police.'
`I take it the police have not succeeded in tracing the lorry?' C. B. asked.
Malouet made a negative gesture. `One could hardly expect them to. Its presence there was not reported till this morning, and the description given of it was only of the vaguest.'
`Then the Canon has got away with the game again,' John commented bitterly. `It is a hundred to one on that having been Upson's seaplane. And how darned clever of them to have planned the timing of the job so well. By delaying his departure till the afternoon, Copely Syle was able to fly practically straight in to Nice, yet give Upson the benefit of last light for crossing the mountains. He must have worked fast, though, to have pulled that one over the huge d'Instruction so soon after his arrival.'
C. B. shrugged. `Two and a half hours should have been ample if the de Grasses had the job already planned and everything prepared for him. Then there is always the possibility that it proved unnecessary to resort to a magical operation. Not all law officers would be above taking a bribe to alter a name in an official document.'
`This man is, I think, an honourable magistrate,' Malouet said. `But one can never be certain of such things. There is, too, the fact that Satanism is world wide in its ramifications; so it is even possible that he is a secret associate of the Canon's, and acted as he did on a simple request.'
`Have you reason to suppose that Black Magic is widely practised down here?' C. B. enquired.
`I would not say that. Among the peasants up in the hill villages sorcery has played its part from time immemorial, and still does so. On the coast there is some sorcery, too, of a quite different type, which is resorted to by people who live here only for the gambling. Inveterate gamblers are always superstitious and easily become the dupes of occulists who promise them aid to win money at the tables. But activities which suggest the presence of genuine Satanists are no more frequent here than in Paris or Marseilles.'
`I asked because I think it very unlikely that the Canon will attempt to tackle this business to night on his own. Even if he doesn't assemble a full coven, he will almost certainly need a few brother warlocks to assist him with the homunculus. It occurred to me that if there are certain people in these parts whom you suspect of being practitioners of the Black Art, we might trace him through them.'
`You have been thinking on the same lines as myself,' Malouet nodded. `There is an antique dealer in
