"I'll see the library first," he said. "Sir James will show me. Fetch Dawkins," he said to Thompson, and he followed Sir James through the house out on to the lawn.

As they entered the library by the French-windows, a tall, sandy man rose from the armchair in which he was seated. He was Inspector Gorton of the Sussex County Constabulary. Malcolm Sage nodded a little absently. His eyes were keenly taking in every detail of the figure sprawling across the writing-table. The head rested on the left cheek, and there was an ugly wound in the right temple from which blood had dripped and congealed upon the table. In the right hand was clutched a small, automatic pistol. The arm was slightly curved, the weapon pointing to the left.

Having concluded his examination of the wound, Malcolm Sage drew a silk-handkerchief from his pocket, shook out its folds and spread it carefully over the blood-stained head of Mr. Challoner.

Sir James looked across at him, appreciation in his eyes. It was one of those little human touches, of which he had discovered so many in Malcolm Sage, and the heads of government departments in Whitehall so few.

Malcolm Sage next proceeded to regard the body from every angle, even going down on his knees to see the position of the legs beneath the table. He then walked round the room and examined everything with minute attention, particularly the key of the door, which Sir James had replaced in its position on the inside. The keyhole on both sides of the door came in for careful scrutiny.

He tried the door of a small safe at the far-end of the room; it was locked. He then examined the fastenings of the French-windows.

Finally he returned to the table, where, dropping on one knee on the left-hand side of the body, he drew a penknife from his pocket, and proceeded with great care and deliberation to slit up the outer seam of the trousers so that the pocket lay exposed.

This in turn he cut open, taking care not to disturb the bunch of keys, which, attached to a chain, lay on the thigh, a little to the left.

The others watched him with wide-eyed interest, the inspector breathing heavily.

Having assured himself that the keys would not slide off, Malcolm
Sage rose and turned to Dawkins:
