CHAPTER XXIII

AN EXPECTED TROUBLE

It was good to be out in the open air, to breathe the pure atmosphere once more. For a long time the Chinaman stalked on ahead until the docks were passed and the Tower Bridge loomed high against the sky. It wanted little till daylight now, and already there was a red glow in the east. But the Chinaman went on and on till he came to the Strand and thence across into Leicester Square, to Oxford Street and behind Gower Street. There were gardens and trees looming ghostly in the morning mist, and before one of the gardens the Chinaman stopped and peered through the high gate. He stood for a moment or two as still as statue, then suddenly he grasped Uzali's arm.

"There," he whispered. "You see yourself."

Without another word he turned and sped silently down the road as if his feet were shod with india-rubber. On Uzali, peeping through the bars of the gate, this defection was lost. He was too intent upon some object which appeared to be creeping across the grass. In a low whisper he called Mercer's attention to it, but the latter could see nothing.

"I forgot you do not possess our eyesight," Uzali murmured. "But there is one of the men I am in search of. What they are doing here I don't know. That is what I mean to find out. Now give me a lift over this gate and stay till I come back. Oh, there is no danger."

In his heart of hearts Mercer did not feel so sure of it. But it was not for him to question Uzali's purpose. To lift the latter over the gate was easy, and a second or two later he was safe on the other side.

"One moment before I go," he said. "I am an utter stranger and have never seen this place before. So far as I can judge this is a fine square with a number of good houses round it. It is not difficult to guess that these fellow-countrymen of mine have their eye upon one of the residences. Now, do you think you could find out the names of some of the residents? Of course, I know it is rather a risky thing to try at this time of the morning, but you might hit upon some unsuspicious policeman who can give you all the information you want."

The request seemed ridiculous, almost farcical, but Mercer promised. Neither was he the less anxious to find out for himself, because a shrewd idea had come into his mind and he resolved to put it to the test. He strode off down the road as if on some important errand and presently he saw a policeman swinging silently along. There was an element of risk in what he was about to do, but Mercer did not hesitate.

"I have been looking for an officer for some time," he said. "I wonder if you could be of assistance to me."
