Captain Trench rose from his seat on the last stroke; Willoughby and Durrance followed his example.
"I shall see you to-morrow," said Durrance to Feversham.
"As usual," replied Harry; and his three guests descended from his rooms and walked across the Park together.

At the corner of Pall Mall, however, they parted company, Durrance mounting St.James's Street, while Trench and Willoughby crossed the road into St.James's Square.

"You know Castleton's address ?" he asked.
"Albemarle Street," Willoughby answered, and added the number.
