He opened the door of his room, switched on the light, had closed the door and was half-way to his dressing-table, when an arm like steel closed round his neck, he was jerked suddenly backward on to the floor, and looked up into the inscrutable face of Gonsalez.

“Shout and you die!” whispered a voice in his ear.

Newton lay quiet.

“I’ll fix you for this,” he stammered.

The other shook his head.

“I think not, if by ‘fixing’ me you mean you’re going to complain to the police. You’ve been under my watchful eye for quite a long time, Monty Newton, and you’ll be amazed to learn that I’ve made several visits to your house. There is a little wall safe behind that curtain”—he nodded towards the corner of the room—“would you be surprised to learn that I’ve had the door open and every one of its documentary contents photographed?”

He saw the fear in the man’s eyes as he snapped a pair of aluminium handcuffs of curious design about Monty’s wrists. With hardly an effort he lifted him, heavy as he was, threw him on the bed, and, having locked the door, returned, and, sitting on the bed, proceeded first to strap his ankles and then leisurely to take off his prisoner’s shoes.

“What are you going to do?” asked Monty in alarm.

“I intend finding out where Miss Leicester has been taken,” said Gonsalez, who had stripped one shoe and, pulling off the silken sock, was examining the man’s bare foot critically. “Ordinary and strictly legal inquiries take time and fail at the end—unfortunately for you, I have not a minute to spare.”

“I tell you she’s gone home.”
