She tried to put the thought out of her mind, but it was too vivid, too insistent.

Again she tried the door, and then, conscious of a faint reflected glow on the cloth-lined roof of the cab, she looked backward through the peep-hole. She saw two great motor-car lamps within a few yards of the cab. A car was following, she glimpsed the outline of it as they ran past a street standard.

They were in one of the roads of the outer suburbs. Looking through the window over the driver's shoulder she saw trees on one side of the road, and a long grey fence. It was while she was so looking that the car behind shot suddenly past and ahead, and she saw its tail lights moving away with a pang of hopelessness. Then, before she realised what had happened, the big car ahead slowed and swung sideways, blocking the road, and the cab came to a jerky stop that flung her against the window. She saw two figures in the dim light of the taxi's head lamps, heard somebody speak, and the door was jerked open.

"Will you step out, Miss Beale," said a pleasant voice, and though her legs seemed queerly weak, she obliged. The second man was standing by the side of the driver. He wore a long raincoat, the collar of which was turned up to the tip of his nose.

"You may go back to your friends and tell them that Miss Beale is in good hands," he was saying. "You may also burn a candle or two before your favourite saint, in thanksgiving that you are alive."

"I don't know what you're talking about," said the driver sulkily. "I'm taking this young lady to her office."

"Since when has the Daily Megaphone been published in the ghastly suburbs?" asked the other politely.

He saw the girl, and raised his hat.

"Come along, Miss Beale," he said. "I promise you a more comfortable ride--even if I cannot guarantee that the end will be less startling."
