I confess that on that night of horror I had no suspicion of foul play, for knowing the great financier as a person of very high standing, I naturally believed the story of his niece’s sudden death. It was not until I found myself in the hospital at St. Malo that I realized how cleverly I had been tricked. The drug had been administered to me in just sufficient dose to ensure that my brain should be affected, and that any story I might afterwards tell should be discredited.
Happily, however, I had now nearly completely recovered. I was the third person known to return to their normal senses after a dose of orosin. Would there be a fourth?
Three further days went past, watchful, anxious days. De Gex was still at Stretton Street, apparently quite unconscious that his hireling Sanz was being kept under close surveillance. Another plot was in progress, without a doubt. Twice again had the elusive Spaniard, who was such a close friend of the notorious Despujol, visited Stretton Street.
It seemed, too, that De Gex, though anxious to return to Italy, still remained in London in the hope that Señor Serrano would arrange for the immediate transfer of the Count’s property.
One could scarcely take up a newspaper without finding that Oswald De Gex had attended this function or that, for he was apparently courting the favours of certain high political personages, no doubt with a view to a place in the next Honours List.
I smiled within myself as I read of all the great man’s doings, of his vast financial interests, of his estates in England and in Italy, and his assistance to the Ministry of Finance of Spain. Often indeed when at home I discussed the situation with Hambledon, yet without the evidence of Gabrielle Tennison we could not act.
Nearly a week had passed since my first meeting with the Spanish lawyer Serrano. Tito Moroni had apparently returned to Italy, for he had not been again to Stretton Street. His last visit there had no doubt resulted in a quarrel with his wealthy client, whom I had suspicions he was blackmailing, for such would undoubtedly be the procedure of a blackguard of his calibre. More than once Rivero seemed anxious to secure the arrest of Mateo Sanz, but I constantly urged him to remain patient. He frequently begged me to reveal the true extent of my knowledge, but I always evaded his questions because I was not yet in a position to make a triumphant coup, and avenge poor Gabrielle.
Daily, hourly indeed, was she in my thoughts. The letters I received from Lyons were the reverse of hopeful. The last one indeed reported that little or no progress had been noted during the weeks she had been under the care of the kindly old professor.
One evening, on returning from the office, I found upon the hall-table a note in Mrs. Tennison’s well-known hand. It had been written from Longridge Road a few hours before, and in it she asked me to call that evening as they had returned from France.
Naturally I lost no time in dashing over to Earl’s Court, and with failing heart I entered the well-remembered artistic little drawing-room where Gabrielle herself, in a cool frock of cream washing silk trimmed with narrow edgings of jade green, rose smiling to greet me.
