The Hand in the Dark

by Arthur J. Rees

"There is the back staircase I told you of, at the end of the corridor. That staircase is never used. The door is kept locked, and the key hangs in a room downstairs. It was the door at the bottom of this staircase which was found unlocked by the butler yesterday evening."

"I'll have a look at it, and then we'll go downstairs. I want to see this bedroom window from outside."

They left the bedroom and proceeded to the end of the corridor, where Caldew pointed out the door at the top of the staircase. Merrington opened it, and went down the stairs. He reappeared after the lapse of a few minutes with dusty hands and cobwebs on his clothes.

"The murderer didn't get in that way," he said. "On the face of it, it seems a plausible theory to suggest that he entered by the locked door and hid himself somewhere in this wing, and escaped after committing the murder by jumping through the bedroom window. But it is impossible to get over your point that if he had entered by the door he would have tried to escape by the same means, not knowing that the door had been locked in the meantime. To do that he must have traversed the corridor twice and gone down and up these back stairs while the guests were coming up the other stairs. He couldn't have done it in the time. He would have been caught—cut off before he could get back. Look at this steep flight of stairs and the length of the corridor! That disposes of the incident of the door. Whoever unlocked it was not the murderer."

Merrington retraced his steps along the corridor. As he walked, his eyes roved restlessly over the tapestry hangings and velvet curtains, and took in the dark nooks and corners which abound in old English country-houses.

"Plenty of places here where a man might hide," he muttered, in a dissatisfied voice.

At the head of the front staircase he paused, and looked over the balusters, as though calculating the distance to the hall beneath. Then he descended the stairs.

It still wanted half an hour to breakfast time. There was no sign of anybody stirring downstairs except a fresh-faced maidservant, who was dusting the furniture in the great hall. She glanced nervously at the groups of police officials, and then resumed her dusting. Merrington strode across to her.

"What is your name, my dear?" he asked, in his great voice.

"Milly Saker, sir."
