“I asked because you didn’t seem quite sure about it before,” explained Cartwright.

There was a faint twinkle in his eye, and Lord Caterham looked at him reproachfully.

“I’ll take you to the Council Chamber,” he said more briskly.

They followed him, the inspector bringing up the rear, and darting sharp glances all around him as he went, much as though he expected to find a clue in a picture frame, or behind a door.

Lord Caterham took a key from his pocket and unlocked a door, flinging it open. They all passed into a big room panelled in oak, with three long windows giving on the terrace. There was a long refectory table and a good many oak chests, and some beautiful old chairs. On the walls were various paintings of dead and gone Caterhams and others.

Near the left-hand wall, about half-way between the door and the window, a man was lying on his back, his arms flung wide.

Dr. Cartwright went over and knelt down by the body. The inspector strode across to the windows, and examined them in turn. The centre one was closed, but not fastened. On the steps outside were footprints leading up to the window, and a second set going away again.

“Clear enough,” said the inspector, with a nod. “But there ought to be footprints on the inside as well. They’d show up plain on this parquet floor.”

“I think I can explain that,” interposed Bundle. “The housemaid had polished half the floor this morning before she saw the body. You see, it was dark when she came in here. She went straight across to the windows, drew the curtains, and began on the floor, and naturally didn’t see the body which is hidden from that side of the room by the table. She didn’t see it until she came right on top of it.”

The inspector nodded.
