In the first place, there was the Peter Hay case. There, at least, the motive was plain enough. Someone had good reason to silence Peter Hay and suppress any evidence which he might give with regard to the Derek Fordingbridge claim. But, unfortunately, at least two people might be supposed to have good grounds for wishing to suppress Peter Hay’s evidence: the claimant and Paul Fordingbridge. Either of them would fit the facts neatly enough.
Then there was the Foxhills’ housebreaking, and the theft of various articles. Obviously the silver was not the important part of the loot, since it was worth next to nothing; and the few odds and ends found in Peter Hay’s cottage must have been planted there merely to confuse the trail. The real thing the thief had wanted was Derek Fordingbridge’s diary. But here again the two possibilities were open. To a false claimant, the diary would be an invaluable mine of information; and, if the man at Flatt’s cottage were an impostor, it was obvious that he would do his best to lay hands on such a treasure. On the other hand, if he were the real Derek, then Paul Fordingbridge would have every interest in suppressing a document which could be utilised to confirm his nephew’s recollections at every point.
The problem of Staveley’s death was a piece of the puzzle which defeated all Wendover’s attempts to fit it into place. Who had an interest in removing Staveley? The Fleetwoods, according to the inspector’s ideas; and Wendover could not help admitting that a jury might look at things from the inspector’s point of view. Undoubtedly he himself had produced enough circumstantial evidence to clear Cressida of even a manslaughter charge, provided that one pinned the prosecution down to the period when she met Staveley on the rock; but Wendover had been thoroughly alarmed by Sir Clinton’s instructions to Armadale; and he feared that he had missed some vital link in the chain of evidence which might overturn his whole case for the defence.
Then there was the alternative hypothesis: that Mme. Laurent-Desrousseaux had been the one to shoot Staveley. Again there seemed to be the double solution open, with no way of deciding which answer to choose. And, to make the matter still more complex, there was the second cartridge-case found at the groyne, which Stanley Fleetwood denied having used. Finally, Sir Clinton most obviously expected to find yet another empty cartridge-case somewhere on the sands. Wendover gave it up. Then a fresh thought struck him. Staveley, as the inspector had hinted, would be a good witness for the claimant; and therefore, making the same assumptions as before, Paul Fordingbridge had an interest in silencing him. But there was no evidence connecting Paul Fordingbridge with the matter at all. That seemed to be a blank end, like all the others.
The next link in the chain of events was the attack on Cargill. The more Wendover considered the matter, the clearer it seemed to him that Cargill had been shot in mistake for the claimant. The two men were very much alike, except for the awful mutilation of the claimant’s face; and, of course, that would not show in the dark. Once the claimant was out of the way, then Paul Fordingbridge would be free from the impending disclosure of his malversations, if these had really occurred.
And, suddenly, a light flashed on Wendover’s mind from a fresh angle. The claimant, Cressida, Paul Fordingbridge—that was the order of inheritance. If by some manoeuvre Paul Fordingbridge could clear out of his way, not the claimant only, but his niece as well, then he himself would come into the estate, and no one could ask any questions whatever. Cressida had been twice involved—once in the affair of Staveley; again when her car came up just after Cargill had been shot. Was it possible that Paul Fordingbridge had tried to kill two birds with one stone in the last crime? The inspector would have been a willing tool in his hands, since he believed Cressida quite capable of murder.
Then there was the disappearance of Paul Fordingbridge himself, with all the puzzle of the footprints. A man didn’t fly; nor did he hand himself over to enemies without some sort of struggle. Had he a couple of confederates who had helped him to stage the whole wilfully mysterious affair on the sands? And what did Sir Clinton mean by his hints about Père François and Sam Lloyd’s “Get off the Earth” puzzle? Wendover recalled that puzzle: two concentric discs with figures on them, and when one disc was revolved on the central pivot, you could count one Chinaman more or less according to where you stopped the disc. Three men when the discs were in one position; two men when you gave a twist to one of the bits of cardboard. Had Sir Clinton some hanky-panky of that sort in his mind, so that the third man on the sands had no real existence? Wendover gave it up.
He returned to the hotel for dinner, and spent as much time as possible in his own room rather than run the gauntlet of inquisitive guests. It was not until after dinner on Wednesday that he was again drawn directly into the game. He was just putting on his coat to go out, in order to escape his inquisitors, when the inspector appeared, evidently in a state of perturbation.
“I’ve just had a wire from Sir Clinton, sir. My old landlady’s let me down badly. I’d warned the post office people to send me any message immediately, but I was out when it came, and the old fool put it behind her kitchen clock and forgot all about it. It wasn’t till I asked her that she remembered about it and gave it to me. Net result: hours wasted.”
He handed a telegram form to Wendover, who read:
