"You are not very original in your methods," she said, "this is the second time you have spirited me off."

"The gaols of England, as your new-found friend Milsom will tell you, are filled with criminals who departed from the beaten tracks," said van Heerden. "Walk out into the corridor and turn to the right. I will be close behind you. A little way along you will discover a narrow passage which leads to the service staircase. Go down that. I am sure you believe me when I say that I will kill you if you attempt to make any signal or scream or appeal for help."

She did not answer. It was because of this knowledge and this fear, which was part of her youthful equipment—for violent death is a very terrible prospect to the young and the healthy—that she obeyed him at all.

They walked down the stone stairs, through an untidy, low-roofed lobby, redolent of cooking food, into the street, without challenge and without attracting undue notice.

Van Heerden's car was waiting at the end of the street, and she thought she recognized the chauffeur as Bridgers.

"Once more we ride together," said van Heerden gaily, "and what will be the end of this adventure for you depends entirely upon your loyalty—what are you opening your bag for?" he asked, peering in the dark.

"I am looking for a handkerchief," said Oliva. "I am afraid I am going to cry!"

He settled himself back in the corner of the car with a sigh of resignation, accepting her explanation—sarcasm was wholly wasted on van Heerden.

"Well, gentlemen," said Milsom, "I don't think there's anything more I can tell you. What are you going to do with me?"
