Yet the fact that she had any connection with the mysterious Italian now lying dead above caused me to ponder. She knew the secret of that incident in quiet old Pisa. Yes. She was a mystery.

Had she told me the actual truth? That was the question which greatly puzzled me.

Through the following day and the next when, with Sammy, I followed the Italian to his lonely grave at Highgate, I recalled every incident of that strange sequence of circumstances, and longed again to see and question her.

Sammy, with that easy irresponsibility which was one of his chief characteristics, declared that Lucie, for obvious reasons, would not show herself again. But, on the other hand, I argued that if his allegation that she had come to Granville Gardens in order to meet me were correct, then she would return. She had, I pointed out, no suspicion that he was there and had recognised her. Therefore there was nothing to prevent her seeking me.

The whole circumstances were both romantic and puzzling.

The very man who she had alleged had plotted with the woman Hardwick against me had entrusted his most valuable possessions to me. Why? Had the small kindness I had shown him turned his heart towards me? Certainly he had paid me for my services—the sum of two hundred pounds.

Once or twice I wondered how I stood legally. The man was dead, yet I had a faint suspicion that I had no legal right whatsoever to administer his estate. There might be a will somewhere, and if legatees came forward I might one day find myself in a very queer and awkward position.

But I told Sammy nothing of this. I deemed it best to preserve silence both as regards the money and the curious packet that I was to keep three years.

A week went by. The man who had given his name as Massari had been interred, the expenses paid, and life at Mrs Gilbert’s had resumed its normal quiet. Indeed, not until three days after the funeral were the other guests let into the tragic secret of the stranger’s sudden death. Then for a day or two the whole place was agog and various theories formed. In London a foreigner is always viewed with a certain amount of suspicion, perhaps on account of our insular proclivities, perhaps because the majority of Londoners know no other language beyond a smattering of elementary French.

Often and often, when alone in our little den at the back of the house, Sammy and I discussed the curious affair, but neither of us was able to arrive at any satisfactory conclusion.
