“They took frightful risks, sir.”
“They took one big risk. I think Giggle left the doors open while he attacked Lord Wutherwood. Tinkerton, in that case, would be quite safe, if she kept her thumb on the call button up above. That would prevent anybody summoning the lift to the ground floor and it would return to the top floor the moment Giggle left it and closed the doors behind him. The great risk was that somebody would come out on the landing and notice that the lift was not there, or catch it on its return, or even see it returning. In that case the job would have been up to Tinkerton. If somebody appeared as the lift was going down, she would have had to keep her thumb on the button and no sooner did it stop than it would return, with Lord Wutherwood angrily alive inside it. If somebody appeared during the few seconds after the attack but before the lift returned, and before Tinkerton got away, she would have had to distract the newcomer’s attention. Ask if she might fetch Lady Wutherwood. Faint, like Lady Macbeth. Slam the hall door on her own finger. Anything to draw attention away from the lift. That was their difficult moment, but it only lasted a few seconds, and remember that Tinkerton knew pretty well what you were all doing. She wouldn’t have been implicated but Giggle would. Giggle was the mug.”
“Why did she kill him?”
“Because he’d lost his nerve. This morning we questioned him about the lift and about his legacy. He went to pieces. He was a stupid fellow, ready enough to act quickly when the brains of the party shoved the weapon in his hand and egged him on, but wildly incapable of keeping his head afterwards, when the mental rot set in. No doubt he returned to Brummell Street in a state of terror and Tinkerton decided he was dangerous. She’s a clever, a desperate and a courageous woman. Moreover she is in her mistress’ confidence. I’ll bet you anything you like that Tinkerton is the buyer of whatever drug Lady Wutherwood takes and that she gets a little commission on the side. As Lady Wutherwood’s confidante, she undoubtedly knows a great deal about the witchcraft business. We shall only find Lady Wutherwood’s prints on the—” Alleyn checked himself — “on the objects connected with this last crime, but I’ll stake my life that Tinkerton visited the kitchen sometime during the night and brought away an instrument which she laid ready to hand in the green drawing-room. You may be sure Tinkerton knew very well what her mistress meant to do during the small hours. You may be sure it was Tinkerton who suggested that Lady Wutherwood should test the power of the Hand of Glory and Tinkerton who slipped down the backstairs and pulled out the fuse plug. One can imagine the instructions that were poured into that demented ear. First she was to secure the hand, then take it up to the top landing and down the deserted passage to the end room. There she would find a sleeping man. Let her make any noise she could think of, drop his heavy boots on the floor, scream, shake the bed. No one would stir, said Tinkerton, for all would be under the soporific spell of the severed hand.”
“So poor Aunt V. was the cat’s-paw.”
“Yes. Tinkerton may even have persuaded her that her Little Master required the death of the chauffeur. She may have told her where to find the razor. Her prints on the razor would be useful and her reaction when she found Giggle already murdered wouldn’t matter. Let her make whatever noise she liked. Let her be found there, with the razor in her hand. I’m sorry, Miss Grey, it’s a beastly story but I think you’ll feel better if you know exactly what happened, however unpleasant the recital.”
“Yes,” said Roberta. “But I still don’t quite see.”
“It may be Aunt V., after all,” said Henry. “Egged on by Tinkerton.”
“No. Only a left-handed person could have done it. I shan’t describe the nature of the injury.”
“I’d rather you did,” said Henry. “Robin, dear, perhaps if you—”
