This needless infliction, coming upon him at the crisis of an adventurous night, infuriated Mr Pickering. He swore softly. He groped round the walls for an electric-light switch, but the shack had no electric-light switch. When there was need to illuminate it an oil lamp performed the duty. This occurred to Mr Pickering after he had been round the place three times, and he ceased to grope for a switch and began to seek for a match-box. He was still seeking it when he was frozen in his tracks by the sound of footsteps, muffled but by their nearness audible, just outside the door. He pulled out his pistol, which he had replaced in his pocket, backed against the wall, and stood there prepared to sell his life dearly.

The door opened.

One reads of desperate experiences ageing people in a single night. His present predicament aged Mr Pickering in a single minute. In the brief interval of time between the opening of the door and the moment when a voice outside began to speak he became a full thirty years older. His boyish ardour slipped from him, and he was once more the Dudley Pickering whom the world knew, the staid and respectable middle-aged man of affairs, who would have given a million dollars not to have got himself mixed up in this deplorable business.

And then the voice spoke.

'I'll light the lamp,' it said; and with an overpowering feeling of relief Mr Pickering recognized it as Lord Wetherby's. A moment later the temperamental peer's dapper figure became visible in silhouette against a background of pale light.

'Ah-hum!' said Mr Pickering.

The effect on Lord Wetherby was remarkable. To hear some one clear his throat at the back of a dark room, where there should rightfully be no throat to be cleared, would cause even your man of stolid habit a passing thrill. The thing got right in among Lord Wetherby's highly sensitive ganglions like an earthquake. He uttered a strangled cry, then dashed out and slammed the door behind him.

'There's someone in there!'

Lady Wetherby's tranquil voice made itself heard.

'Nonsense; who could be in there?'
