"Here is this one then. In Padua, which seems to be regaining its old reputation as the birthplace of spurious antiques, by the way, there lives an ingenious craftsman named Pietro Stelli. This simple soul, who possesses a talent not inferior to that of Cavino at his best, has for many years turned his hand to the not unprofitable occupation of forging rare Greek and Roman coins. As a collector and student of certain Greek colonials and a specialist in forgeries I have been familiar with Stelli's workmanship for years. Latterly he seems to have come under the influence of an international crook called--at the moment--Dompierre, who soon saw a way of utilizing Stelli's genius on a royal scale. Helene Brunesi, who in private life is--and really is, I believe--Madame Dompierre, readily lent her services to the enterprise." "Quite so," nodded Mr Carlyle, as his host paused. "You see the whole sequence, of course?" "Not exactly--not in detail," confessed Mr Carlyle. "Dompierre's idea was to gain access to some of the most celebrated cabinets of Europe and substitute Stelli's fabrications for the genuine coins. The princely collection of rarities that he would thus amass might be difficult to dispose of safely but I have no doubt that he had matured his plans. Helene, in the person of Nina Bran, an Anglicised French parlourmaid--a part which she fills to perfection--was to obtain wax impressions of the most valuable pieces and to make the exchange when the counterfeits reached her. In this way it was obviously hoped that the fraud would not come to light until long after the real coins had been sold, and I gather that she has already done her work successfully in several houses. Then, impressed by her excellent references and capable manner, my housekeeper engaged her, and for a few weeks she went about her duties here. It was fatal to this detail of the scheme, however, that I have the misfortune to be blind. I am told that Helene has so innocently angelic a face as to disarm suspicion, but I was incapable of being impressed and that good material was thrown away. But one morning my material fingers--which, of course, knew nothing of Helene's angelic face--discovered an unfamiliar touch about the surface of my favourite Euclideas, and, although there was doubtless nothing to be seen, my critical sense of smell reported that wax had been recently pressed against it. I began to make discreet inquiries and in the meantime my cabinets went to the local bank for safety. Helene countered by receiving a telegram from Angiers, calling her to the death-bed of her aged mother. The aged mother succumbed; duty compelled Helene to remain at the side of her stricken patriarchal father, and doubtless The Turrets was written off the syndicate's operations as a bad debt."
