In face of that my only conclusion was that, after leaving Florence, they had suddenly changed the course of their flight.

Their flight! Why had Mabel fled from me, after speeding so swiftly to meet me? Ay, that was the crucial question.

Late one afternoon I was standing upon the Pincian, leaning upon the balustrade of that popular promenade of the Romans, and watching the crowd of winter idlers who, in carriage and afoot, were taking the fresh, bright air. I had been there every day, hoping against hope either to recognise Mabel or the man Kirk among the crowd of wealthy cosmopolitans who thronged the hillside.

Before me moved the slow procession of all sorts and conditions of carriages, from the gaudily-coloured, smart motor-car of the young Italian elegant to the funereal carozza of the seedy marchesa, or the humble vettura of the tweed-skirted “Cookite.” Behind showed the soft grey rose of the glorious afterglow with the red roofs, tall towers and domes of the Eternal City lying deep below. Against the sky stood the tall cypresses—high, gloomy, sombre—and over all spread that light film of mist that rises from old Tiber when the dusk is gathering.

The scene was, perhaps, one of the most picturesque in all Italy, even surpassing that from the Piazza Michelangelo in Firenze, but to me, hipped and bewildered as I was, the chatter in a dozen tongues about me was irritating; and I turned my back upon the crowd, leaning my elbows upon the stone parapet, and gazing over the gay, light-hearted capital whence at that moment came up the jangling of bells started by the great bell at St. Peter’s and echoing from every church tower, the solemn call to evening prayer that is, alas! ever unheeded. In modern Italy only the peasant is pious; in the alto mondo religion is unfashionable.

Perhaps you have driven in the Corso, that narrow and most disappointing of thoroughfares, gossiped in the English tea-shop at five o’clock, taken your vermouth and bitters in the Aregno, and climbed the Pincian to see the sunset. If you have, then you know that life, you recognise amid that crowd faces of both sexes that you have seen at Aix, at Vichy, at Carlsbad, at Ostend, or in the rooms at Monte Carlo, many of them vicious, sin-hardened faces, careless, indolent, blasé; few, alas! with the freshness of youth or the open look indicated by pure-mindedness.

On the Pincian you have the light-hearted thoughtless world which exists only to be amused, the world which laughs at grim poverty because it obtains its wherewithal from the labours of those poor, underpaid and sweated millions in other countries who must work in order that these few favoured ones may indulge in their extravagances.

Sick to death, disappointed, worn out by a continual vigilance and with a deep anxiety gnawing ever at my heart-strings, I had turned from the scene, and was gazing across into the rose-tinted mists, when of a sudden I heard a voice at my elbow, exclaiming in broken English:

“Why, surely it’s the Signor Holford!”

I turned quickly, and to my amazement found myself confronted by the thin, sinister face of the dead Professor’s servant, Antonio Merli.
