The other men present on that occasion were all acquaintances of mine, two of them financiers in the City whose names were well known on the Stock Exchange, a third the heir to an earldom to which he had since succeeded, and the fourth Sir Charles Webb, a smart young Guardsman of the modern type. After a dinner of that exquisite character of which Burton Blair’s French chef was famous, we all drove to the Empire, and afterwards spent a couple of hours at the Grosvenor Club, concluding the evening at the Bachelors, of which Sir Charles was a member.

Now as I stood within the hushed gloom of that grand old church, watching the dark mysterious figure pacing the aisle in patience and awaiting the person who would never come, I recollected what had, on that evening long ago, aroused within me a curious feeling of resentment against him. It was this. Having left the Empire, we were standing outside on the pavement in Leicester Square calling cabs, when I overheard the Italian exclaim in his own language to Blair, “I do not like that friend of yours—Greenwood. He is far too inquisitive.” At this my friend laughed, saying, “Ah, caro mio, you don’t know him. He is my very best friend.” The Italian grunted, replying, “He has been putting leading questions to me all the evening, and I have had to lie to him.” Again Blair laughed. “It is not the first time you’ve committed that sin,” was his answer. “No,” the other responded in a low voice, intending that I should not overhear him, “but if you introduce me to your friends be careful that they are not quite so astute or so inquisitive as this man Greenwood. He may be a good fellow, but even if he is he surely must not know our secret, if he did, it might mean ruin to us, remember!”

And then, before Blair could make response, he mounted into a hansom which at that moment had pulled up at the kerb.

From that moment I had entertained a distinct dislike of the man who had been introduced to me as Salvi, not that I hold every foreigner in suspicion as some insular Englishmen so foolishly do, but because he had endeavoured to poison Blair’s mind against me. Yet after a week the incident had entirely slipped my memory and I had never recollected it until that strange and unexpected re-encounter.

Was it possible that this monk with the sun-bronzed, bearded face was the same man who rented that apartment in the Florence slum, and whose visits there were so surreptitious and mysterious? Perhaps so, because all the secrecy of his habitation would be accounted for by the fact that a Capuchin is not allowed to possess any property outside his monastery. Those infrequent visits to Florence might be made at times when, being a lay brother, he would no doubt be sent out into the country to collect from the contadini alms and presents in kind for the poor in the city. Everywhere throughout Tuscany, in peasant’s hut as in prince’s palace, the humble, patient and charitable Capuchin is welcomed; a flask of wine and a crust is ready for him at the house of every contadino, and in the villas and palaces of the rich there is always a place for him in the servants’ hall. How many of the Italian poor are saved annually from sheer starvation by the soup and bread dispensed daily at the door of every Capuchin monastery, it would be impossible to estimate. Suffice it to say that the Order in their snuff-coloured habits and their black skull-caps is the greatest and truest friend the starving poor possesses.

Babbo Carlini was no doubt idling outside upon the steps of the church awaiting my reappearance. Would he, I wondered, recognise in this monk the description he had obtained of Paolo Melandrini, the unknown man who was to be Mabel Blair’s secretary and adviser?

The last loiterers in the antique Chapel of the Holy Sacrament had left, their footsteps echoing away across the flags to the exit, and I found myself alone with the silent, almost statuesque, man beside whom I had, only one year before stood in the Grand Circle at the Empire watching and criticising a ballet.

Should I address him and claim acquaintance? His openly-expressed disapproval of myself caused me to hesitate. It was quite apparent that he had held me in apprehension on that night at Grosvenor Square, therefore in the present circumstances his suspicion would undoubtedly become increased. Should I boldly address him and thus show my fearlessness, as well as my acquaintance with his subterfuges? or should I withdraw and watch his subsequent movements?

I at length decided on the former course—for two reasons. The first was that I felt confident he had recognised me as Burton’s friend; and the second because in dealing with such a man the open declaration of knowledge is always the more advantageous in the end than the careful concealment of such facts as I already knew. If I set a watch upon him his suspicions would become heightened, whereas if I acted openly I might succeed in disarming him.

Therefore, turning upon my heel, I strolled straight towards where he had halted as though he were patiently awaiting Blair’s arrival.
