The Duchess was not only a believer in the existence of a sunken treasure of alluring proportions; she also believed that she knew of a method by which the said treasure might be precisely located and cheaply disembedded. An aunt on her mother’s side of the family had been Maid of Honour at the Court of Monaco, and had taken a respectful interest in the deep-sea researches in which the Throne of that country, impatient perhaps of its terrestrial restrictions, was wont to immerse itself. It was through the instrumentality of this relative that the Duchess learned of an invention, perfected and very nearly patented by a Monegaskan savant, by means of which the home-life of the Mediterranean sardine might be studied at a depth of many fathoms in a cold white light of more than ball-room brilliancy. Implicated in this invention (and, in the Duchess’s eyes, the most attractive part of it) was an electric suction dredge, specially designed for dragging to the surface such objects of interest and value as might be found in the more accessible levels of the ocean-bed. The rights of the invention were to be acquired for a matter of eighteen hundred francs, and the apparatus for a few thousand more. The Duchess of Dulverton was rich, as the world counted wealth; she nursed the hope, of being one day rich at her own computation. Companies had been formed and efforts had been made again and again during the course of three centuries to probe for the alleged treasures of the interesting galleon; with the aid of this invention she considered that she might go to work on the wreck privately and independently. After all, one of her ancestors on her mother’s side was descended from Medina Sidonia, so she was of opinion that she had as much right to the treasure as anyone. She acquired the invention and bought the apparatus. Among other family ties and encumbrances, Lulu possessed a nephew, Vasco Honiton, a young gentleman who was blessed with a small income and a large circle of relatives, and lived impartially and precariously on both. The name Vasco had been given him possibly in the hope that he might live up to its adventurous tradition, but he limited himself strictly to the home industry of adventurer, preferring to exploit the assured rather than to explore the unknown. Lulu’s intercourse with him had been restricted of recent years to the negative processes of being out of town when he called on her, and short of money when he wrote to her. Now, however, she bethought herself of his eminent suitability for the direction of a treasure-seeking experiment; if anyone could extract gold from an unpromising situation it would certainly be Vasco—of course, under the necessary safeguards in the way of supervision. Where money was in question Vasco’s conscience was liable to fits of obstinate silence.
