own personal safety. I don't believe him. So I'm calling on him.'

'You're wasting your time,' Hardanger said heavily. 'MacDonald is above suspicion. Long, distinguished and spotless record. Spent twenty minutes this morning going over it.'

'I've read it,' I said. 'Some of the star turns in the Old Bailey over the past few years have had immaculate records — until the law caught up with them.'

'He's a highly respected character locally,' Wylie put in. 'Bit of a snob, associates only with the very best people, but everyone speaks very well of him.'

'And there's more to his record than you've read, Cavell,' Hardanger went on. 'In the report there's only a brief mention of his wartime service in the Army but it so happens I'm a personal friend of the colonel who commanded MacDonald's regiment in the last two years of the war. I rang him up. Dr. MacDonald, it seems, has been strangely reticent about himself. Did you know that as a second lieutenant in Belgium in 1940 he won the D.S.O. and the bar, that he finished up as a lieut-colonel in a tank regiment with a string of medals as long as your arm?'

'I didn't and I don't get it,' I admitted. 'He struck me as a phoney-tough type, who, if ever he'd done any valorous deeds, wouldn't have been backward about admitting them. He wanted me to think he was afraid: he didn't want me to think he was brave. Why? Because he knew he had to justify his heavy drinking so he put it down to personal fear. But, in view of his record, it almost certainly wasn't that. Queer item number one. Queer item number two — why wasn't all this listed in his security report. Easton Derry compiled most of those dossiers — and Derry would be unlikely to overlook so large a gap in a man's history.'

'I don't know about that,' Hardanger admitted. 'But this much is certain — if the report I had on MacDonald is correct then on the face of it it seems highly unlikely that a man so brave, selfless and patriotic could possibly be mixed up in anything like that.'

'This colonel of MacDonald's regiment who told you about him — could you get him down here immediately?'

Hardanger let me have his cool speculative look. 'Thinking he's a phoney in every sense? That this man's been substituted for the real MacDonald?'

'I don't know what to think. We must have another squint at his record card and check that Derry really did compile it.'

'We can soon fix that,' Hardanger nodded. This time he was on the phone for almost ten minutes and when he'd finished with that so had Mary with my face and I was all ready to go. Hardanger said, 'You look bloody awful but I wouldn't recognise you if I saw you in the street. The file's in the safe in my hotel. Shall we go there?'

I turned to leave the room. Hardanger took a look at the palms and fingers of my hands, still slowly welling blood from the hack-saw scratches. He said irritably, 'Why didn't you have the doctor bandage your fingers as well? Want to get blood poisoning?'

'Have you ever tried to use a gun with your fingers bandaged together?' I asked sourly.

'Well, man, a pair of gloves then. That's ridiculous.'

'Just as bad. Couldn't get a finger through the trigger guard.'

'Rubber gloves,' he said impatiently. 'Plastic.'

'It's a point,' I agreed. 'Certainly it would hide those damn scratches.' I stared at him without seeing him then sat down heavily on the bed. 'Hell's bells!' I said softly.

I sat very still for a few seconds. Nobody spoke. I went on, speaking more to myself than anyone else, 'Rubber gloves. To cover the scratches. Then why not elastic stockings? Why not?' I looked up vaguely and saw Hardanger glancing at Wylie, maybe thinking that they had let the doctor go too soon, but Mary came to my rescue.

She touched my arm and I turned to look at her. Her face was set and the big green eyes wide with apprehension and the birth of an unpleasant certainty.

'Mordon,' she whispered. 'The fields round it. Gorse, they're covered with gorse. And she was wearing elastic stockings, Pierre.'

'What in heaven's name—' Hardanger began harshly.

'Inspector Wylie,' I interrupted. 'How long would it take you to get an arrest warrant? Murder. Accessory.'

'No time at all,' he said grimly. He patted his breast pocket. 'I have three of them here already signed. Like you said yourself, there are times when we can't wait for the law. We fill 'em in. Murder, eh?'

'Accessory.'

'And the name?' Hardanger demanded. He still wasn't sure that he shouldn't be calling the doctor.

'Dr. Roger Hartnell,' I said.

CHAPTER NINE

'What in the name of God are you talking about?' Dr. Roger Hartnell, a young man with a face suddenly old and tired and strained, stared at us, then at his wife who was standing rigidly beside them, then back at us again. 'Accessory after murder. What are you talking about, man?'

'It's our belief that you know well enough what we are talking about,' Wylie said calmly. It was the Inspector's bailiwick and it was he who had just read out the charge and was making the formal arrest. He went on, 'I have to warn you that what you say now may be used against you at your trial. It would help us if you made a full confession now, I admit: but arrested men have their rights. You may wish to take legal advice before you speak.' Like hell he was going to take legal advice: he was going to talk before he left that house and Hardanger, Wylie and I all knew it.

'Will someone please explain what this — this nonsense is about?' Mrs. Hartnell said coldly. The slightly supercilious incomprehension, the well-bred distaste were done to a turn, but the hostile rigidity of the figure overdone, the gripping hands so tightly clasped that the tremor showed. And she was still wearing the elastic stockings.

'Gladly,' Wylie said. 'Yesterday, Dr. Hartnell, you made a statement to Mr. Cavell here to——'

'Cavell?' Hartnell did some more staring. 'That's not Cavell.'

'I didn't like my old face,' I said. 'Do you blame me? Inspector Wylie is talking, Hartnell.'

'— to the effect,' Wylie went on, 'that you made a late trip night before last to see Mr. Tuffnell. Intensive investigation has turned up several people who were in a position to have seen you had you travelled in the direction you said you did at the time you said you did. Not one of those people saw you. That's point number one.' And quite a good point it was, too, even if the purest fiction: the check had been made all right, but not a single witness found to confirm or deny Hartnells story, which had been just as expected.

'Point number two,' Wylie went on. 'Mud was found last night under the front mudguard of your motor- scooter, a mud which seems to be identical with the red loam found locally only outside Mordon. We suspect you went there early in the evening to reconnoitre. Your machine is at present being moved to police laboratories for tests. Point number——'

'My scooter!' Hartnell looked as if a bridge had fallen on him. 'Mordon. I swear to——'

'Number three. Later that night you took your scooter— and wife — to a spot near Chessingham's house. You almost gave yourself away to Mr. Cavell — you said that the policeman alleged to have seen you on your scooter could back up your story about the trip to Alfringham and then you remembered, almost too late, that if he had seen you he would also have seen your wife on the pillion seat. We found the imprint of your scooter's wheels among bushes not twenty yards from where the Bedford had been abandoned. Careless, Doctor, very careless. I note you're not protesting that one.' He couldn't. We'd found the imprints less than twenty minutes previously.

'Points four and five. Hammer used to stun the guard dog. Pliers used to cut the Mordon fence. Both found last night in your tool-shed. Again by Mr. Cavell.'

'Why, you filthy, sneaking, thieving—' His face twisted, the hair-trigger control suddenly snapped and he flung himself at me, clawed hands outstretched. He didn't get three feet, Hardanger and Wylie just moved in massively from either side and pinned him helplessly between their bulks. Hartnell struggled madly, uselessly, his insane fury increasing. 'I took you in here, you — you swine I entertained your wife. I did—' His voice weakened
