There was no need that he should remember the time⁠—the date was positively established by his master’s order-book. I felt at once that the means were now in my power of striking down the whole conspiracy at a blow with the irresistible weapon of plain fact. Without a moment’s hesitation, I took the proprietor of the livery stables aside and told him what the real importance was of the evidence of his order-book and the evidence of his driver. An arrangement to compensate him for the temporary loss of the man’s services was easily made, and a copy of the entry in the book was taken by myself, and certified as true by the master’s own signature. I left the livery stables, having settled that John Owen was to hold himself at my disposal for the next three days, or for a longer period if necessity required it.

I now had in my possession all the papers that I wanted⁠—the district registrar’s own copy of the certificate of death, and Sir Percival’s dated letter to the Count, being safe in my pocketbook.
