He never thought of the dishonesty of it all. Like his friend, he feared only the consequences of discovery.

"Rot! Of course the thing'll pass. Don't be an ass," growled Rawlings. "Let's sprint off at once. We've time to see him now and still be in for call-over."

Everything seemed to be working in their favour, for the wily Tunstall was at home, and tumbled to their meaning instantly. He was a shock-headed, unkempt individual, with a crooked back and a chin which seemed to have settled down on his chest from infancy. A straggling beard depended from the same chin, while long, untidy eyebrows overshadowed a pair of cunning orbs.

"Say as you was here the whole afternoon, a drinkin' corfee and sich like; of course, Mr. Rawlings," he leered, "but—well, yer see, bein' only a poor man, with this here shop to depend on, I can't afford to give nuffin away, don't yer see, nuffin, not even a promise."

"But we'll make that all right," came the instant and eager response. "Look here, Tunstall, what's it worth?"

The wily one screwed his eyes up till his long brows mingled almost with his unkempt beard. "What's it worth? Well, see here, supposin' I don't stick to the tale. Supposin'——But you ain't yet told me why you've axed for this here alibi. Is it a robbery?"

"A robbery!" shouted Trendall angrily, his fat cheeks wabbling and flushing red. "What do you take us for?"

Tunstall might easily have replied that he took them for what they showed themselves to be. But he had his own terms to make, and caution was necessary.

"No offence, gents," he said silkily. "No offence, I'm sure. I wasn't thinkin' that, of course. But what's the reason for wantin' this here alibi? You've got into some sort o' mess, I suppose. What mess, then? I has to ask, 'cos I has to protect myself, and besides, though I may only keep a small shop, I've got me own feelin's, and me own pride."

The task was not so easy a one as Rawlings imagined. Or, to be precise, that young gentleman was not half as clever as he thought himself. Had he been so he would have seen through the artifices of this rascal at once, and would not have shown concern at his lack of keenness to undertake the work asked of him.
