`I don't understand,' Dalrye muttered in a dull voice,' `I don't know why he came back..
`Perhaps,' said Dr Fell, `I can tell you. Sit quietly for a moment, boy, and rest yourself…. Hadley, do you see now?'
'You mean.?'
`I mean this. When Driscoll stood there at the Traitors' Gate, at the Tower of London, talking to Mrs Bitton at one-thirty, he remembered something. The recollection of it startled him nearly out of his wits. He said he had to go and attend to it. What did he remember?'
`Well?' queried Hadley.
`Think back! He was talking to her, and he mentioned something, about his uncle. That was what made him remember, for his outburst followed it. Think!'
Hadley sat up suddenly. `My God! it was the afternoon of his uncle's monthly visit to him!'
.''Exactly. Bitton didn't intend making the call, but Driscoll didn't know that. He'd forgotten that visit. And Bitton had a key to his flat. He would walk in there, and there, in the flat with no attempt to hide them, were the two hats he had stolen. That was bad enough. But if Bitton grew suspicious, and searched, and found his manuscript
Hadley nodded. `He had to get back to his flat to head off Sir William.'
`He couldn't explain to Laura Bitton, you see. And, if he could, he couldn't take the time. So he did what many another man has done with a woman. He shooed her away and said he would join her in five minutes. Of course, with out any idea of doing it….’
`And do you see what he did? Remember your plan of the Tower, Hadley. He couldn't walk along Water Lane towards the main gate. That way led only to the way out; he couldn't have pretended an errand, and it would have roused the woman's suspicions. So he went the other way along Water Lane, and out of the other gate to Thames Wharf — unnoticed in the fog. That was at half past one.
`You yourself told me, Hadley, that by Underground a person could go to Russell Square in fifteen minutes or even less. And it seemed to me, if Mrs Bitton could do it at five o'clock, why couldn't Driscoll have done it at one- thirty? He would arrive at the flat, in short, about ten minutes to two or a trifle later. the time the police surgeon said he died. But, you see, where all your calculations went wrong was in assuming Driscoll had never left the Tower. The possibility never entered your head. I don't think we should have found a warder who saw him go out, even if we had tried, at that side gate. But the thing simply didn't occur to anybody.'
`But he was found on the Traitors' Gate! I… Never mind,' said Hadley. `Do you feel like going on, Dalrye?'
`So that was it,' the other said, dully. `I see. I see now. I only thought he might have suspected me….
`Let me tell you what I did. He was dead. I saw that. And for a second I went into a sheer panic. I saw that I'd committed a murder. I had already prepared the way for a theft, and I was in deeply enough,' but here was a murder. Nobody would believe it had been an accident. And where I made my mistake was this: I thought Driscoll had told them at the Tower he was coming back there! I could only imagine that they knew! And I had already definitely proved that I was at the flat, because I'd spoken to Parker on the telephone. I thought Driscoll had just changed his mind, and returned — and there I was with the body, when everybody knew we were both there.'
He shuddered.
`Then my common sense came back all in a rush. I had only one chance. That was to get his body away from this flat, somehow, and dump it somewhere out in the open. Somewhere, say, on the way to the Tower — so that they would think he'd been caught on the way back.
`And it all came to me in a flash — the car. The car was in that garage, not far away. The day was very foggy. I could get the car and drive it into the courtyard with the side-curtains on. Phil's body was as light as a kitten. There were only two flats on the floor; and the windows overlooking the court were blank ones; with the fog to help me, there wasn't great danger of being seen Dr Fell looked at Hadley. `Quite right. The chief inspector was positive on that point, too, when he was considering how Mrs Bitton could have got out of the flat. I think he remarked that a Red Indian in a war bonnet could have walked out of that court without being observed. It was suggestive.' `Well… ' Again Dalrye rubbed his eyes unsteadily. `I hadn't much time. The thing to do was to save time by shooting over to the garage by the Underground — I could do it, with luck, in two minutes, where it would have taken me ten to walk to get the car, and come back for the body.
`I don't know what sort of face I put up in front of those garage people. I told them I was going home, rolled out, and shot back to the flat. If I'd been arrested then… ' He swallowed hard. `I took up Phil's body and carried it out. That was a ghastly time; carrying that thing. My God! I nearly fell down those little steps, and I nearly ran his head through the glass door. When I'd got him stowed in the back of the car, under a rug, I was so weak I thought I hadn't any arms. But I had to go back to the flat to be sure I hadn't overlooked anything. And when I looked round, I got an idea. That top-hat. If I took that along, and put it on Phil… why, you see, they would think the Mad Hatter had killed him! Nobody knew who the hat-thief was. I didn't want to get anybody else in trouble, and that way it was perfectly safe…'
`The chief inspector,' said Dr Fell, 'will have no difficulty understanding you. You needn't elaborate. He had just finished outlining the same idea himself, as being the murderer's line of thought, before you came in. What about the crossbow bolt?'
'I–I left the bolt… you know where. You see, I'd never seen the damn thing before. I didn't know it came from Bitton's house. I simply assumed it was one of Phil's possessions and couldn't do anybody harm. I didn't see the Souvenir de Carcassonne, because you know why. It was hidden.'
Dalrye's nostrils grew taut. His hands clenched on his knees and his voice went high. `But one thing I remembered before I left that flat. I remembered that manuscript in my pocket. I might have killed Phil. I might have been the lowest swine on earth, and I was pretty sure I was. But, by God! I wasn't, going to put dirty dollars in my pocket by selling that manuscript to Arbor now. It was in my pocket. I took it out. I was so wild that I was going to tear it up and take a; handful of the pieces along to throw in Bitton's face. But if I tore it up here… oh, well. They'd find the pieces, and there wasn't any use doing Phil dirt, even if I had killed him. I knew I was wasting time, but I touched a match to it and threw it in the grate…. I had the top hat, squashed flat, under my coat, and I thought I'd attended to everything.'
`You should have put back the fender in its place,' said Dr Fell. '`Nobody, merely searching that flat could have shoved a solid iron fender round the way you did when you had your fight with Driscoll. Well?'
`Then,' said Dalrye, reaching automatically after the whisky, `then I had the first of my two really horrible shocks. When I was just getting outside' the door of the flat, I ran into the porter. I said, 'Ha, ha, or something of the sort, and told him what a good fellow, he was, and for no reason at all I handed him half-a-crown. He walked out to the car with me….'
`Son,' said Dr Fell, with, a sudden grunt, 'you told an unnecessary lie to-day, and that car gave you away. When you were telling your story to us at the Tower this afternoon, you said you had never taken the car to the flat at all. You said when you left the flat you had to go to the garage and get it, and then start home. Still, I suppose you couldn't say anything else. But when Mr Hadley here explained this evening about your having the car there, as the porter told him.. No matter. Then?'
`I drove away. I'd put the top-hat on Phil, and stuffed his cap into my pocket. All I had to do was find a side lane somewhere down near the Tower, and pitch him out in the — fog. I didn't bother about fingerprints, for, as God is my judge, I'd never touched that crossbow bolt…. And then, just as I'd laid my plans, and I was getting away from Bloomsbury, do you know what happened?'
'Yes,' said Hadley. `You met General Mason.'
`Met him? Met him? Do you think I'd have stopped if I'd seen him? The first thing I knew he'd hopped on the running board, and there he was grinning at me, and saying what a godsend this was, and telling me to get over in the front seat, so that he had room to shove in beside me….
`I stopped the car dead. I felt as though the whole car started to collapse under me. I tried to move, and my foot, jumped so much on the accelerator that I stalled the car. Then I turned my, head away and glared out of the side as though I were looking at a tyre.
`Then the car got started somehow. I could hear the General talking, but I don't remember anything he said. He was in a very good humour, I know, and that seemed, to make it worse.
`I was headed for destruction now I could- see that. We should go straight back to the Tower, and no power this side of hell could change it. Straight back…. Excuse me a second… a drink. Funny this stuff doesn't seem to
