The following day three stalwart men descended from the quick train from London and chartered a fly to drive them to Lord Vansittart's.

"A fine place," said one, almost regretfully--he was young, with a fresh colour, and his errand seemed ghastly to him--as they drove in at the open gates, past a lodge which was to all appearance empty.

"Yes," said the eldest of the trio. "Dear me," he added, looking out as the fly passed out of the lime avenue. "What a melancholy looking house! All the blinds down, too!"

Arriving at the hall-door, the oldest and sternest-looking emerged and asked to see Lord Vansittart. The porter looked impressed, but unhesitatingly admitted him, and conducted him to the library, leaving him with a grave "I will tell his lordship."

"Strange; he did not ask who I was or what I wanted," murmured the man to himself. The silence in the great mansion was almost oppressive. He heard the servant's footsteps, distant voices, the clang of a closing door, then a slight pattering, which grew gradually more distinct, and seemed to keep pace with the beats of his pulse. Advancing footsteps!

"They have heard, and they have all gone; the man is coming back with some fine tale or another," he told himself, exasperatedly. As the door opened he turned with ready resentment, which gave place to a startled, uncomfortable sensation as in the ghastly man in deep black who entered he recognised Lord Vansittart.

"I am very sorry, my Lord, but I have a most painful duty to perform," he began, taking the warrant from his pocket. "I am compelled to arrest Lady Vansittart for the wilful murder of Victor Mercier on the --th of June last."

Lord Vansittart bowed, asked to see the warrant, and then slowly said, "If you will come this way, I will take you to her ladyship, who has a complete answer to the charge."

The detective bowed, passing his hand across his lips to assure himself that he was not smiling--he had no wish to wound the wretched husband of a miserable murderess--and followed the proprietor of the richly-furnished mansion across the hall, up the grand staircase, and along the corridor. Vansittart paused at a door, opened it, and entered.
