Before Jim could recover from his astonishment at seeing the man whom he had been led to believe was upon the high seas, standing before him, the cabman had whipped up his horse once more, and was half across the Circus. Springing to his feet, he pushed up the shutter, and bade the driver pull up as quickly as possible. Then, jumping from the cab, he gave the man the first coin he took from his pocket.

"Did you see which way that fellow went we so nearly knocked down?" he cried.

"Went away towards Regent Street, I believe," answered the cabman. "He had a narrow shave and it isn't his fault he isn't in hospital now."

Jim waited to hear no more, but made his way back to the policeman he had noticed standing beside the fountain in the centre of the Circus.

"Did you see that man who was so nearly knocked down by a cab a few minutes ago?" he enquired, scarcely able to speak for excitement.

"I did," the officer answered laconically. "What about him?"

"Only that you must endeavour to find him, and arrest him at once," said Jim. "There is not a moment to be lost. He may have got away by this time."

"And he's precious lucky if he has," said the policeman. "Never saw a closer thing in my life."

"But don't you hear me? You must find him at once. Every second we waste is giving him the chance of getting away."

"Come, come, there's no such hurry: what's he done that you should be so anxious to get hold of him?"
