"I don't know, sir," said Southwick, his subordinate. "There's always a chance that a crook will do the obviously wrong thing. I suppose you've no theory as to where they have gone?"

"Not out of town—of that I'm certain," said King, "that is why the quest is so hopeless. Why, they'll have got to their destination hours before the message went out!"

They were standing in the girl's bedroom, which still reeked with chloroform, and all the clues were piled together on the table. There were not many. There was a pad of cotton-wool, a half-empty bottle of chloroform, bearing the label of a well-known wholesaler, and one of a pair of old wash-leather gloves, which had evidently been worn by somebody in his desire to avoid leaving finger-prints.

"We've not much to go on there," said Stafford disconsolately; "the chloroform may have been sold years ago. Any chemist would have supplied the cotton-wool, and as for the glove"—he picked it up and looked at it carefully, then he carried it to the light.

Old as it was, it was of good shape and quality, and when new had probably been supplied to order by a first-class glove-maker.

"There's nothing here," said Stafford again, and threw the glove back on the table.

A policeman came into the room and saluted.

"I've cycled over from the Yard, sir. We have had a message asking you to go at once to Sir Stanley Belcom's private house."

"How did Sir Stanley know about this affair?" asked Stafford listlessly.

"He telephoned through, sir, about five o'clock this morning. He often makes an early inquiry."
