"On May 21, 1792," says Gamain, according to the "Bibliophile Jacob," "whilst I was working in my shop, a horseman drew up at my door and called me out. His disguise as a carter did not prevent me from recognising Durey, the King's forge assistant. I refused. I congratulated myself that evening at having done so, as the rumour spread in Versailles that the Tuileries had been attacked by the mob, but this did not really take place till a month later. Next morning Durey returned and showed me a note in the King's own hand, entreating me to lend my assistance in a difficult job past his unaided powers. My pride was flattered. I embraced my wife and children, without telling them whither I was going, but I promised to return that night. It was not without anxiety that they saw me depart with a stranger for Paris." We need merely point out that Durey was no stranger to the family: he had been for years associated daily with Gamain. "Durey conducted me to the Tuileries, where the King was guarded as in a prison. We went at once to the royal workshop, where Durey left me, whilst he went to announce my arrival. Whilst I was alone, I observed an iron door, recently forged, a mortise lock, well executed, and a little iron box with a secret spring which I did not at once discover. Then in came Durey with the King. 'The times are bad,' said Louis XVI., 'and I do not know how matters will end.' Then he showed me the works I had noticed, and said, 'What do you say to my skill? It took me ten days to execute these things. I am your apprentice, Gamain.' I protested my entire devotion. Then the King assured me that he always had confidence in me, and that he did not scruple to trust the fate of himself and his family in my hands. Thereupon he conducted me into the dark passage that led from his room to the chamber of the Dauphin. Durey lit a taper, and removed a panel in the passage, behind which I perceived a round hole, about two feet in diameter, bored in the wall. The King told me he intended to secrete his money in it, and that Durey, who had helped to make it, threw the dust and chips into the river during the night. Then the King told me that he was unable to fit the iron door to the hole unassisted. I went to work immediately. I went over all the parts of the lock, and got them into working order; then I fashioned a key to the lock, then made hinges and fastened them into the wall as firmly as I could, without letting the hammering be heard. The King helped as well as he was able, entreating me every moment to strike with less noise, and to be quicker over my work. The key was put in the little iron casket, and this casket was concealed under a slab of pavement in the corridor."
