“He’s one of the most ingenious of all the army of secret agents. Indeed, I have a suspicion that he is the chief of the French spies operating in England. His intimate acquaintance with your friend Miss Austin shows conclusively that he is contemplating a big coup.”
Had this matter, I wondered, any connection with the gigantic conspiracy of which the Princess had told me? My promise of secrecy given to her prevented me from mentioning it to Kaye. Only a few weeks ago the Figaro had announced that Her Highness the Princess Léonie von Leutenberg had left the Château de Chantoiseau, and had returned to her mansion in the Frieung, in Vienna. She had left France without sending me a word.
“What connection had this man Bertini with the exposure of the Ceuta negotiations?” I inquired.
“He got to know of them by some means—how, I can’t tell. It is an absolute enigma.”
“And that despatch I brought from London, the exact contents of which were known a few hours after my return here, what of that?”
“Through him, I feel assured,” answered the clever man before me. “I only returned from London three days ago. I went myself to make inquiries.”
“And what did you find?”
“He carries on the business of a jeweller, and has a small shop half-way up the Edgware Road, one of those cheap Brummagem places that sell earrings and brooches for servant-girls. He poses as quite a respectable shopkeeper, and employs an Englishman as manager. The signor, it appears, has many friends in London, and when they call to see him they are always shown to his private room over the shop. I also learnt that your visitor of to-day has called upon him there.”
“Are you sure?” I cried quickly. “Are you absolutely certain of that?”
“I gave her description and name to the manager, who said he recollected her calling there twice about three weeks ago. Once his master was not in, but on the second occasion she had an interview with him. It has more than once struck me as curious that this fellow Bertini should have been near you on the day of the mysterious theft of the contents of that despatch. You don’t think that he followed you from Ryburgh to London?”
