“I’d rather know, too, Henry. It’s beastly to wonder.”
“Well,” said Alleyn, “the murderer stood behind the head of the bed and the angle and position of the injury precludes any possibility of it being a right-handed attack. That’s all you need to know, isn’t it?”
“But why didn’t she arrange it to look like suicide?” asked Henry and Alleyn saw with astonishment that the passionate interest of the amateur had already replaced in Henry’s mind the horror of the scene with Lady Wutherwood. Henry had not seen Giggle and so, though he lay upstairs with his throat slit, his injury had an academic interest and Henry was prepared to discuss it.
“Tinkerton was very careful that it should not look like suicide,” Alleyn said. “A theory of suicide might have led to the possibility of Giggle’s complicity and that would have come altogether too close to Tinkerton. No. Tinkerton was desperate. With Giggle in a state of terror, blundering in his statements to the police, threatening perhaps to confess and be hanged, she had to revise her plans drastically and disastrously. We must now be led to plump for Lady Wutherwood as a homicidal maniac. The whole object of the first crime went west but Tinkerton was in terror of her life. She made up her mind to cut her losses and Giggle’s throat.”
“Won’t it be very hard to prove all this, sir?”
“If Miss Grey hadn’t heard the lift and if you both had slept through the night, we should have had little against her beyond the left-handed evidence and her earlier lies. As it is you heard Lady Wutherwood downstairs and saw her come upstairs and go to the top landing on the errand that was to be thought murderous. But when Campbell followed her to the chauffeur’s bedroom and found her there with the body Giggle had been dead for over two hours. We’ve medical evidence for that. It was half past two then. The nurse will swear that at one o’clock Lady Wutherwood was in bed and had not stirred. The nurse had her cocoa in a thermos flask. Tinkerton brought it to her at eleven o’clock. The previous night she drank it immediately. To-night she was about to drink it, she had actually set out her cup and saucer before Tinkerton went away, when the storm reminded her that she had left the window open in the next room. She shut the window, decided to write a letter and forgot her cocoa. She did not drink it until two hours later. In the meantime Tinkerton had killed Giggle. The nurse drank her cocoa at two o’clock and immediately fell into a deep sleep.”
“How much did Aunt V. know?”
“She knew, at least, that she must keep still and pretend to be asleep for as long as the nurse was waking. She had been well instructed, it seems. She has made one statement. I’m afraid it will not be much use as evidence but it is illuminating. Dr. Curtis tells me she has said over and over again: ‘Why were they not asleep? She said they would all sleep like the dead.’ And when he asks her: ‘Who said this?’ she answers ‘Tinkerton’!”

“Well, that’s over,” said Charlot, raising her black hat until it perched on her grey curls and tipped over her nose. “I must say that we do look a collection of old black crows.”
