"I would rather you dropped me at the Tube," she replied. "I have nearly two hours before I need go to the theatre. I'm not on until the second act."

Despard pretended to be bitterly disappointed that Miss Strode was deserting them. Ruby surreptitiously handed Rupert the money she had in her purse and whispered to him that she would get their winnings in the morning and bring them round to his rooms. She had no reason for secrecy, and so he asked her to give him the ticket she had received from the bookmaker when she had backed Ambuscade.

"I don't like the idea of your going round to the bookmaker's offices. It's possible they'll dispute it, or make a fuss," he said.

Despard agreed and suggested that they should meet at ten o'clock in the morning and all go round in a body. But Ruby was obstinate and refused to give up the ticket.

"I backed the horse myself. I am going to get the money and bring it round to Rupert!"

She got quickly out of the cab as it stopped at the Piccadilly Tube Station and, blowing a kiss to Rupert, she disappeared in the crowd.

The two men drove to the grillroom of the Savoy.

"You are a lucky devil," Despard said, "if there's no mistake, and Miss Strode really backed Ambuscade."

"Why should there be a mistake?" Rupert asked curtly.

"Oh, I don't know!"—Despard shrugged his shoulders—"but she seemed rather mysterious about it. Perhaps that's a woman's way. They are queer cattle."
