'Nor I. Why, it must have been done in this room, while the safe was open, while I was actually present. That is the only solution possible. Again, who has been in this room?' 'All the callers--I read their names to you--your clients.' 'They all sit in that chair. They never leave that chair so long as they are with me.' He indicated the chair which stood at the corner of the lawyer's great table at his left hand. Now the safe was in the far corner, on the other side of the room. 'They could not possibly---- Checkley, the only two who could possibly have access to that safe in office hours are yourself and Mr. Arundel.' 'Good heavens! sir--you can't believe--you can't actually think----' 'I believe nothing. I told you so before. I think nothing. I want the facts.' The room was long rather than square, lit by two large windows, overlooking the gardens of New Square, Lincoln's Inn. The lawyer sat with his back to the fire, protected by a cane-screen, before a large table. On his left hand, at the corner of the table, stood the clients' chair: on his right hand, between the two windows, was a small table with a couple of drawers in it. And in the corner, to the left of any one writing at the small table, and on the right hand of the lawyer, was the open safe already mentioned. There were two doors, one communicating with the clerk's room, the other opening directly on the stairs. The latter was locked on the inside. 'Call Mr. Arundel,' said the chief. While Checkley was gone, he walked to the window and observed that any one sitting at the table could, by merely reaching out, take anything from the safe and put it back again unobserved, if he himself happened to be occupied or looking another way. His grave face became dark. He returned to his own chair, and sat thinking, while his face grew darker and his eyes harder, until Mr. Arundel appeared.
