'Yes, he slipped the stuff into a whisky and soda which Mr. Wade had downstairs before retiring to bed. That's why he was already feeling sleepy when he wrote that letter to Miss Wade.'
'Then the footman, Bauer, hadn't anything to do with it?' asked Bundle.
'Bauer was one of our people, Lady Eileen. It was thought likely that our crook would go for Herr Eberhard's invention and Bauer was got into the house to watch events on our behalf. But he wasn't able to do much. As I say, Mr. Thesiger administered the fatal dose easily enough. Later, when everyone was asleep, a bottle, glass and empty chloral bottle were placed by Mr. Wade's bedside by Mr. Thesiger. Mr. Wade was unconscious then, and his fingers were probably pressed round the glass and the bottle so that they should be found there if any questions should arise. I don't know what effect the seven clocks on the mantelpiece made on Mr. Thesiger. He certainly didn't let on anything to Mr. Devereux. All the same, I think he had a bad five minutes now and again thinking of them. And I think he kept a pretty wary eye on Mr. Devereux after that.
'We don't know exactly what happened next. No one saw much of Mr. Devereux after Mr. Wade's death. But it is clear that he worked along the same lines that he knew Mr. Wade had been working on and reached the same result – namely, that Mr. Thesiger was the man. I fancy, too, that he was betrayed in the same way.'
'You mean?'
'Through Miss Loraine Wade. Mr. Wade was devoted to her – I believe he hoped to marry her – she wasn't really his sister, of course – and there is no doubt that he told her more than he should have done. But Miss Loraine Wade was devoted body and soul to Mr. Thesiger. She would do anything he told her. She passed on the information to him. In the same way, later, Mr. Devereux was attracted to her, and probably warned her against Mr. Thesiger. So Mr. Devereux in turn was silenced – and died trying to send word to the Seven Dials that his murderer was Mr. Thesiger.'
'How ghastly,' cried Bundle. 'If I had only known.'
'Well, it didn't seem likely. In fact, I could hardly credit it myself. But then we came to the affair at the Abbey. You will remember how awkward it was – specially awkward for Mr. Eversleigh here. You and Mr. Thesiger were hand in glove. Mr. Eversleigh had already been embarrassed by your insisting on being brought to this place, and when he found that you had actually overheard what went on at a meeting, he was dumbfounded.'
The Superintendent paused and a twinkle came into his eye.
'So was I, Lady Eileen. I never dreamed of such a thing being possible. You put one over on me there all right.
'Well, Mr. Eversleigh was in a dilemma. He couldn't let you into the secret of the Seven Dials without letting Mr. Thesiger in also – and that would never do. It all suited Mr. Thesiger very well, of course, for it gave him a bona fide reason for getting himself asked to the Abbey, which made things much easier for him.
'I may say that the Seven Dials had already sent a warning letter to Mr. Lomax. That was to ensure his applying to me for assistance, so that I should be able to be on the spot in a perfectly natural manner. I made no secret of my presence, as you know.'
And again the Superintendent's eyes twinkled.
'Well, ostensibly, Mr. Eversleigh and Mr. Thesiger were to divide the night into two watches. Really, Mr. Eversleigh and Miss St. Maur did so. She was on guard at the library window when she heard Mr. Thesiger coming and had to dart behind the screen.
'And now comes the cleverness of Mr. Thesiger. Up to a point he told a perfectly true story, and I must admit that with the fight and everything, I was distinctly shaken – and began to wonder whether he had had anything to do with the theft at all, or whether we were completely on the wrong track. There were one or two suspicious circumstances that pointed in an entirely different direction, and I can tell you I didn't know what to make of things, when something turned up to clinch matters.
'I found the burnt glove in the fireplace with the teeth marks on it – and then – well – I knew that I'd been right after all. But, upon my word, he was a clever one.'
'What actually happened?' said Bundle. 'Who was the other man?'
'There wasn't any other man. Listen, and I'll show you how in the end I reconstructed the whole story. To begin with, Mr. Thesiger and Miss Wade are in this together. And they have a rendezvous for an exact time. Miss Wade comes over in her car, climbs through the fence and comes up to the house. She's got a perfectly good story if anyone stops her – the one she told eventually. But she arrived unmolested on the terrace just after the clock had struck two.
'Now, I may say to begin with that she was seen coming in. My men saw her, but they had orders to stop nobody coming in – only going out. I wanted, you see, to find out as much as possible. Miss Wade arrives on the terrace, and at that minute a parcel falls at her feet and she picks it up. A man comes down the ivy and she starts to run. What happens next? The struggle – and presently the revolver shots. What will everyone do? Rush to the scene of the fight. And Miss Loraine Wade could have left the grounds and driven off with the formula safely in her possession.
'But things don't happen quite like that. Miss Wade runs straight into my arms. And at that moment the game changes. It's no longer attack but defence. Miss Wade tells her story. It is perfectly true and perfectly sensible.
'And now we come to Mr. Thesiger. One thing struck me at once. The bullet wound alone couldn't have caused him to faint. Either he had fallen and hit his head – or – well, he hadn't fainted at all. Later we had Miss St. Maur's story. It agreed perfectly with Mr. Thesiger's – there was only one suggestive point. Miss St. Maur said that after the lights were turned out and Mr. Thesiger went over to the window, he was so still that she thought he must have left the room and gone outside. Now, if anyone is in the room, you can hardly help hearing their breathing if you are listening for it. Supposing, then, that Mr. Thesiger had gone outside. Where next? Up the ivy to Mr. O'Rourke's room – Mr. O'Rourke's whisky and soda having been doped the night before. He gets the papers, throws them down to the girl, climbs down the ivy again, and – starts the fight. That's easy enough when you come to think of it. Knock the tables down, stagger about, speak in your own voice and then in a hoarse half-whisper. And then, the final touch, the two revolver shots. His own Colt automatic, bought openly the day before, is fired at an imaginary assailant. Then, with his left gloved hand, he takes from his pocket the small Mauser pistol and shoots himself through the fleshy part of the right arm. He flings the pistol through the window, tears off the glove with his teeth, and throws it into the fire. When I arrive he is lying on the floor in a faint.'
Bundle drew a deep breath.
'You didn't realise all this at the time, Superintendent Battle?'
'No, that I didn't. I was taken in as much as anyone could be. It wasn't till long afterwards that I pieced it all together. Finding the glove was the beginning of it. Then I made Sir Oswald throw the pistol through the window. It fell a good way farther on than it should have done. But a man who is right-handed doesn't throw nearly as far with the left hand. Even then it was only suspicion – and a very faint suspicion at that.
'But there was one point struck me. The papers were obviously thrown down for someone to pick up. If Miss Wade was there by accident, who was the real person? Of course, for those who weren't in the know, that question was answered easily enough – the Countess. But there I had the pull over you. I knew the Countess was all right. So what follows? Why, the idea that the papers had actually been picked up by the person they were meant for. And the more I thought of it, the more it seemed to me a very remarkable coincidence that Miss Wade should have arrived at the exact moment she did.'
'It must have been very difficult for you when I came to you full of suspicion about the Countess.'
'It was, Lady Eileen. I had to say something to put you off the scent. And it was very difficult for Mr. Eversleigh here, with the lady coming out of a dead faint and no knowing what she might say.'
'I understand Bill's anxiety now,' said Bundle. 'And the way he kept urging her to take time and not talk till she felt quite all right.'
'Poor old Bill,' said Miss St. Maur. 'That poor baby had to be vamped against his will – getting madder 'n a hornet every minute.'
'Well,' said Superintendent Battle, 'there it was. I suspected Mr. Thesiger – but I couldn't get definite proof. On the other hand, Mr. Thesiger himself was rattled. He realised more or less what he was up against in the Seven Dials – but he wanted badly to know who No. 7 was. He got himself asked to the Cootes under the impression that Sir Oswald Coote was No. 7.'
'I suspected Sir Oswald,' said Bundle, 'especially when he came in from the garden that night.'
'I never suspected him,' said Battle . 'But I don't mind telling you that I did have my suspicions of that young
