As the words left the man's mouth, they were passing a well-lit brasserie. A tall, cadaverous man passed them and Hugh had a suspicion that they exchanged glances of recognition.
Was his pretended friend an agent of the police?
For a few seconds he debated within himself how he should act. To refuse to do as he was bid might be to bring instant arrest upon himself. If the stranger were actually a detective--which he certainly did not appear to be--then the ruse was to get him on the road to Cette because the legal formalities were not yet complete for his arrest as a British subject.
Yet he knew all about The Sparrow, and his attitude was not in the least hostile.
Hugh could not make up his mind whether the stranger was an associate of the famous Sparrow, or whether he was very cleverly inveigling him into the net.
It was only that exchange of glances with the passer-by which had aroused Hugh's suspicions.
But that significant look caused him to hesitate to accept the mysterious stranger as his friend.
True, he had accepted as friends numbers of other unknown persons since that fateful night at Monte Carlo. Yet in this case, he felt, by intuition, that all was not plain sailing.
"Very well," he said, at last. "I esteem it a very great favour that you should have interested yourself on behalf of one who is an entire stranger to you, and I heartily thank you for warning me of my danger. When I see The Sparrow I shall tell him how cleverly you approached me, and how perfect were your arrangements for my escape."
