“I have no ticket,” said Chester, quietly, handing the man a sovereign. “I had not time to go to the booking-office. I got in at Bineleigh. This lady will bear me out.”

The man quickly wrote a receipt and handed it with the change. Then the train glided on once more, and in a few minutes they were in the great terminus.

“You have no carriage waiting?” Chester asked.

“No,” she said quietly; “I’ll take a cab.”

Chester summoned one, and handed her in.

“Where do you wish to be driven?” he said.

“Home.”

“May I come with you, or must I follow in another cab?” he asked.

“I am at your mercy, Dr Chester,” she replied sadly.

He hesitated for a moment, then told the driver the name and number of the street, and sprang in.
