Walking down the passage which led to the great square hall, Anthony pondered. It seemed impossible that this gigantic imperturbability was a murderer. But how to explain the finger-prints? And Deacon did not know of those prints. What would he do when told of them? “The man’s in a mess,” he said to himself. “This week’s problem: how to extricate him? The solution will be published in our next week’s issue—per-haps!” He came out into the hall. The utter silence of the house oppressed him. Any sound, he thought, would be welcome, would make things seem less like a nightmare. He turned to his left, making for the verandah door. His fingers on its handle, he paused. Behind him, to his right, was the door of the study. His ears had caught a sound, a rustling sound, from that direction. He looked about him. No one was near, in sight even. The two men Boyd had left on duty had disappeared. Quietly, he crossed to the study door. He laid his ear against it. He heard the click of a lock, a light lock, then a rustle of paper, then soft footsteps. He crossed the hall to the foot of the stairs in three jumps. A barometer and a clock hung on the wall. He studied them. He heard the study door open, slowly, as if the one who opened were anxious not to be noisy. Then came a rustle of skirts. He stepped out from the shadow. Half-way between the study and where he stood by the foot of the stairs was a woman. Her hand, which had been at the bosom of her dress, fell to her side. Anthony moved towards her. Closer, he saw her more plainly—a tall, square-shouldered grenadier of a woman, with a sexless, high-cheekboned, long-nosed face. The features, the sand-coloured hair, were reminiscent of the dead minister. “Miss Hoode?” Anthony bowed. “My name is Gethryn. I believe that Sir Arthur Digby-Coates has explained my presence.” “Yes.” The woman’s tones were flat, lifeless as her face. She essayed cordiality. “Yes, indeed. I told him I was glad, very glad, to have your help. I need to apologise for not having spoken to you before, but—I—but——” Anthony raised a hand. “Believe me, madam, I quite understand. I would like, if it is not an impertinence, to express my condolence.” The woman bowed her head. “Thank you,” she said; pressing a hand to her heart. “I—I must leave you. Give orders for anything you may want.” Anthony watched her mount the stairs and disappear. “My good woman—if you really are a woman—what’s your trouble? Sorrow? Or fear? Or both?” he thought. “And why were you in the study? And why were you so secret about it? And above all, what did you hide in your flat bosom when you saw me? Two whats and two whys.”
