He returned to the front of the house, and seeing that the catch of one of the windows was not fastened, he threw up the lower sash, hoisted his suit-case over the sill, and himself dropped into the room. The table was laid for lunch, but nothing had been used.

"Rummy go!" said Burton to himself.

Conscious of a smell of burning, he crossed the passage, and glanced in at Micklewright's den, then at the kitchen, where the air was full of the fumes of something scorching. A saucepan stood on the dying fire. Lifting the lid, he saw that it contained browned and blackened potatoes. He opened the oven door, and fell back before a cloud of smoke impregnated with the odour of burnt flesh.

"They must have been called away very suddenly," he thought. "Perhaps there's a telegram that explains it."

He was returning to his friend's room when he was suddenly arrested by a slight sound within the house.

"Who's there?" he called, going to the door.

From the upper floor came an indescribable sound. Now seriously alarmed, Burton sprang up the stairs and entered Micklewright's bedroom. It was empty and undisturbed. The spare room which he was himself to occupy was equally unremarkable. Once more he heard the sound: it came from the housekeeper's room.

"Are you there?" he called, listening at the closed door.

He flung it open at a repetition of the inarticulate sound. There, on the bed, lay the old housekeeper in a huddled heap, her hands and feet bound, and a towel tied over her head. This he removed in a moment.
