"I confess I could see nothing myself when the tracker first got off; but half a glance was enough for him; and on he went like a blood-hound, with his black muzzle close to the ground, the rest of us keeping a bit behind and well on one side. Presently there's a foot-print I can see for myself, then more that I simply couldn't, then another plain one; and this time Billy—they're all called Billy—simply jumped with joy. At least I thought it was with joy, till I saw him pointing from his own marks to the others, and shaking his black head. Both prints were about the same depth.

"'Him stamp,' says Billy. 'What for him stamp?'

"But we pushed on and came to some soft ground where any white fool could have run down the tracks; and presently they brought us to a fence, which we crossed by strapping down the wires and leading our horses over, but not where Rigden had led his. Well, we lost the tracks eventually where Rigden said he'd lost them, at what they're pleased to call a 'tank' in these parts; the black fellow went round and round the waterhole, but devil another footmark could he find. So then we went back on the tracks we had found. And presently there's a big yabber-yabber on the part of William, who waddles about on the sides of his feet to show his bosses what he means, and turns in his toes like a clown.

"Well, I asked the sergeant what it was all about; but he wouldn't tell me. And it was then that this fellow Spicer began to play the fool: he had smelt the rat himself, I suppose. He made a still greater ass of himself at the fence, where the blackfellow messed about a long time over Rigden's marks when we got back there. After that we all came marching home, or rather riding hell-to-leather. And the fun became fast and furious; so to speak, of course; for I needn't tell you it was no fun for me, Moya."

"Quite sure? Well, never mind; go on."

"There was no end of a row. Harkness and Myrmidons entered the barracks, and Spicer ordered them out. They insisted on searching Rigden's room. Spicer swore they shouldn't, and appealed to me. What could I do, a mere visitor? I remonstrated, advised them to wait, and so forth; further resistance would have been arrant folly; yet that madman Spicer was for holding the fort with the station ordnance!"

"Go on," said Moya again: she had opened her lips to say something else, but the obvious soundness of Theodore's position came home to her in time.

"Well, the long and short of it is that the sergeant came to me on the verandah with the very pair of boots with which the tracks had been made; a heel was off one of them; they were too small for Rigden, yet they were found hidden away in his room. The astounding thing is that the blessed blackfellow had spotted that the tracks were not made by the man to whom the boots belonged. He had turned in his toes and walked on the outside of his feet; it wasn't so with the trail they followed up to these pines yesterday; and diamond had cut diamond about as neatly as you could wish to see it done. It was smart of Rigden to run alongside his horse and make it look as though he were riding alongside the trail; but it wouldn't do for the wily savage, and I'm afraid the result will be devilish unpleasant."

There was no fear, however, in the clean-cut and clean-shaven face, nor did Theodore's tone suggest any possible unpleasantness to him or his. Moya could have told him so in a manner worthy of himself, but again she showed some self-restraint, and was content to thank him briefly for putting her in possession of all the facts.

"Ah!" said Theodore, "I only wish I could do that! You talked a little while ago about my suspecting the truth; well, I give you my word that I haven't even yet the ghost of an idea what the real truth can be."
