"Forgery," was the laconic answer. "He belongs to a pretty well-known gang, and we have had our suspicions of him for a long time now, but he was devilish clever and cunning. Several of his pals were caught, but it was always difficult to rope him in. We shouldn't have got him now but for the fact of one of his pals peaching. And even now, although the evidence is strong enough for us, I doubt if it is strong enough to get him more than a comparatively light sentence. If he can lay hold of a clever counsel, and there will be some money at the back of him, if not a great deal, he won't come off so badly." So Mr. Burton was a criminal, and had been living in Blankfield on the proceeds of his nefarious calling. The rich uncle in Australia who had left him a comfortable fortune was a myth. "I suppose he has been on the 'crook' all his life?" queried Hugh. "Ever since he has come under our observation," was the reply of the detective. "Before he joined the present gang, a few of whom we have collared from time to time, card-sharping was his lay. Once he rented an expensive flat in Paris, and I believe made a tidy bit out of it. That is where the young lady first appeared upon the scene." "But how long ago is that? She doesn't look more than twenty." "I know," said Mr. Davidson. "She looks wonderfully young, that is one of her assets. As a matter of fact I should say she was twenty-four at the least. The Parisian episode occurred about five years ago, making her nineteen at the time. He was there about twelve months, at the end of which time he got an introduction to the forging gang, and chucked the cards in favour of a more remunerative game." "She acted, I suppose, as a decoy and confederate?" "So I am given to understand. She very seldom played herself, but used to signal the opponents' cards to him." "What a precious pair," groaned Hugh. He had long been doubtful of them, but he had never anticipated this. "Now, Captain Murchison, there is a little question I want to ask you," said the detective briskly, after a brief pause. "My pal and I only arrived here yesterday, but we have not been idle, we have picked up a good deal. We have discovered that nobody in Blankfield visits them, except yourself and another officer, a Mr. Pomfret. That is true, is it not?" "Quite true," assented Murchison. "You frequently go to their house together. But perhaps I may be telling you something you don't know when I say that Mr. Pomfret more frequently has gone alone." "I have had my suspicions some time," was Hugh's answer. "Now tell me, please; I suppose in the evenings you played cards, or roulette, or some game of chance. I thought so. Did you lose much? Had you any suspicions they were rooking you?" "On my first visit, a suspicion that they might do so crossed my mind. But nothing of the sort was attempted. I should say that, up to the present, my friend and I stand a bit to the good. Evidently, that was not their object."
