I looked at my companion in surprise. He was either telling the truth, or else he was endeavoring to allay my suspicions by an extremely clever ruse. Now I had already decided that Philip Hornby was no eccentric, but a particularly level-headed and practical man. Therefore I instantly arrived at the conclusion that the clean-shaven fellow who looked so much like a London barrister had some distinct and ulterior purpose in arousing within my mind suspicion of his host's sanity.

It was past midnight when, having bade the strange pair adieu, I was put ashore by the two sailors who had rowed me out and drove home along the sea-front, puzzled and perplexed.

Next morning, on my arrival at the Consulate, old Francesco, who had entered only a moment before, met me with blanched face, gasping-

"There have been thieves here in the night, signore! The Signor Console's safe has been opened!"

"The safe!" I cried, dashing into Hutcheson's private room, and finding to my dismay the big safe, wherein the seals, ciphers and other confidential documents were kept, standing open, and the contents in disorder, as though a hasty search had been made among them.

Was it possible that the thieves had been after the Admiralty and Foreign Office ciphers, copies of which the Chancelleries of certain European Powers were ever endeavoring to obtain? I smiled within myself when I realized how bitterly disappointed the burglars must have been, for a British Consul when he goes on leave to England always takes his ciphers with him, and deposits them at the Foreign Office for safekeeping. Hutcheson had, of course, taken his, according to the regulations.

Curiously enough, however, the door of the Consulate and the safe had been opened with the keys which my friend had left in my charge. Indeed, the small bunch still remained in the safe door.

In an instant the recollection flashed across my mind that I had felt the keys in my pocket while at dinner on board the Lola. Had I lost them on my homeward drive, or had my pocket been picked?

Carducci, with an Italian's volubility, commenced to hurl imprecations upon the heads of the unknown sons of dogs who dared to tamper with his master's safe, and while we were engaged in putting the scattered papers in order the door-bell rang, and the clerk went to attend to the caller.

In a few moments he returned, saying-

"The English yacht left suddenly last night, signore, and the Captain of the Port has sent to inquire whether you know to what port she is bound."

"Left!" I gasped in amazement "Why, I thought her engines were disabled!"

A quarter of an hour later I was sitting in the private office of the shrewd, gray-haired functionary who had sent this messenger to me.

"Do you know, Signor Commendatore," he said, "some mystery surrounds that vessel. She is not the Lola, for yesterday we telegraphed to Lloyd's, in London, and this morning I received a reply that no such yacht appears on their register, and that the name is unknown. The police have also telegraphed to your English police inquiring about the owner, Signor Hornby, with a like result. There is no such place as Woodcroft Park, in Somerset, and no member of Brook's Club of the name of Hornby."

I sat staring at the official, too amazed to utter a word. Certainly they had not allowed the grass to grow beneath their feet.

"Unfortunately the telegraphic replies from England are only to hand this morning," he went on, "because just before two o'clock this morning the harbor police, whom I specially ordered to watch the vessel, saw a boat come to the wharf containing a man and woman. The pair were put ashore, and walked away into the town, the woman seeming to walk with considerable difficulty. The boat returned, and an hour after, to the complete surprise of the two detectives, steam was suddenly got up and the yacht turned and went straight out to sea."

"Leaving the man and the woman?"

"Leaving them, of course. They are probably still in the town. The police are now searching for traces of them."

"But could not you have detained the vessel?" I suggested.

"Of course, had I but known I could have forbidden her departure. But as her owner had presented himself at the Consulate, and was recognized as a respectable person, I felt that I could not interfere without some tangible information-and that, alas! has come too late. The vessel is a swift one, and has already seven hours start of us. I've asked the Admiral to send out a couple of torpedo-boats after her, but, unfortunately, this is impossible, as the flotilla is sailing in an hour to attend the naval review at Spezia."

I told him how the Consul's safe had been opened during the night, and he sat listening with wide-open eyes.

"You dined with them last night," he said at last. "They may have surreptitiously stolen your keys."

"They may," was my answer. "Probably they did. But with what motive?"

The Captain of the Port elevated his shoulders, exhibited his palms, and declared-

"The whole affair from beginning to end is a complete and profound mystery."

That day was an active one in Questura, or police office, of Leghorn.

Detectives called, examined the safe, and sagely declared it to be burglar-proof, had not the thieves possessed the key. The Foreign Office knew that, for they supply all the safes to the Consulates abroad, in order that the precious ciphers shall be kept from the prying eyes of foreign spies. The Questore, or chief of police, was of opinion that it was the ciphers of which the thieves had been in search, and was much relieved to hear that they were in safekeeping far away in Downing Street.

His conjecture was the same as my own, namely, that the reason of Hornby's call upon me was to ascertain the situation of the Consulate and the whereabouts of the safe, which, by the way, stood in a corner of the Consul's private room. Captain Mackintosh, too, had taken his bearings, and probably while I sat at dinner on board the Lola my keys had been stolen and passed on to the scarred Scotsman, who had promptly gone ashore and ransacked the place while I had remained with his master smoking and unsuspicious.

But what was the motive? Why had they ransacked all those confidential papers?

My own idea was that they were not in search of the ciphers at all, but either wanted some blank form or other, or else they desired to make use of the Consular seal. The latter, however, still remained on the floor near the safe, as though it had rolled out and been left unheeded. As far as Francesco and I could ascertain, nothing whatever had been taken. Therefore, we re-arranged the papers, re-locked the safe and resolved not to telegraph to Hutcheson and unduly disturb him, as in a few days he would return from England, and there would be time enough then to explain the remarkable story.

One fact, however, we established. The detective on duty at the railway station distinctly recollected a thin middle-aged man, accompanied by a lady in deep black, passing the barrier and entering the train which left at three o'clock for Colle Salvetti to join the Rome express. They were foreigners, therefore he did not take the same notice of them as though they had been Italians. Inquiries at the booking-office showed, however, that no passengers had booked direct to Rome by the train in question. To Grossetto, Cecina, Campiglia, and the other places in the Maremma, passengers had taken tickets, but not one had been booked to any of the great towns. Therefore it was apparent that the mysterious pair who had come ashore just prior to the sailing of the yacht had merely taken tickets for a false destination, and had re-booked at Colle Salvetti, the junction with that long main line which connects Genoa with Rome.
