d about to stop, but the young man's coolness saved him.
For just as they were hesitating he turned off the narrow pavement into
the road and crossed diagonally toward them.

"Can you direct me to Vincent Square?" he said.

One of the constables gave the route, with the firsts and seconds to
right and left, and as Chester and Marion were passing, the young man
said shortly--"Thanks, I see," and they heard his step behind, while the
police continued their way down the mews.

"I'll take a cab as soon as we get a little farther away. Try and be
calm," whispered Chester. "Your brother has escaped."

"Is--is he followed?" said Marion, faintly.

He heard her draw her breath painfully, and as he glanced sideways he
could read in her face the effort she was making.

She saw that he was watching her, and met his eyes firmly.

"Do you think Rob will escape?" she asked.

"I feel sure that he will. The police did not know him by sight. But
he was only just in time. A few seconds more, and he--we--must have
been taken."

She was silent for a time, and then she said bitterly, "I ought not to
have left him, poor fellow! It was cowardly at such a time."

"You did quite right," said Chester, firmly. "Your presence would have
