'Chang, Chang, of all people, eating his supper, and writing as he does so. If only I dared.'
If only he had none others to think of, save himself, David could have shot the man where he sat, though such an act would have gone hard against his conscience and his ideas of what was proper and fair play. But there was Dick to be considered, and Dick was somewhere in the building.
'Mustn't wait,' he told himself, 'no good to be obtained by staring down at that fellow. Chang was the name he gave himself. I shall remember, and one of these days I shall hope to meet him under different circumstances. Now for those other windows.'
He slipped back to his old position, crawled to the edge of the roof on to which he had at first climbed, and hung his head over it. Yes, there was a long row of windows, all in darkness, any of which might give access to the cell in which his comrade was a prisoner.
'Can't remember which I came from myself,' he groaned. 'But I'll try the lot of them. First thing is to get down, then I'll make my way from one to the other.'
To an active lad the task was nothing out of the ordinary, and in a little while David was seated on the edge of one at the far corner of the building. He peered at once into the interior, and, with the aid of the moon's rays, was able to make out the opposite wall and the actual dimensions of the place. It appeared to be empty, but the dark shadow directly beneath him might contain someone. He called Dick's name gently, repeating it till he was sure that he could not be there.
'Even if he were asleep he'd hear that,' he told himself. 'But even Dick, the happy-go-lucky Dick, wouldn't be asleep now. This business would be far too upsetting for any man. I'll get along to the next. Ah! not there. That's the crib from which I so lately scrambled.'
There was no doubt on the last question, for the moonbeams played on the platter of food and the jar of water which had been brought to him, and he realised that this was indeed the cell he had so lately vacated, for the two objects were in precisely the same position in which he had seen them placed. More than that, the edge of the huge basket which had contained his own perspiring and wriggling body was peeping out of the shadow. At once he went crawling on again, peeping into four other cells, only to find each one tenantless. Then a gentle hail from below attracted his attention.
