had laid himself out to conceal the identity of his enemy he could
scarcely have done it more effectually. Baffled in one direction, I
turned for assistance to another. In other words, I interviewed his
left-hand neighbour, a lady with whom I had already had some slight
acquaintance. Our conversation took place across the fence that
separated the two properties.

"Do you happen to be aware," I asked, when we touched upon the one
absorbing topic, "whether the unfortunate gentleman had ever been
in Europe?"

"He had been almost everywhere," the woman replied. "I believe he was a
sailor at one time, and I have often heard him boast that he knew almost
every seaport in the world."

"I suppose you never heard him say whether he had lived in Italy?" I
inquired.

"He used to mention the country now and again," she said. "If it was a
fine morning he would sometimes remark that it was a perfect Italian

I was about to thank her and move away when she stopped me with an

Italy, and that the letter was for the gentleman next door. 'The next
time I see him,' I said to myself, 'I'll ask him for that stamp for
Willie.' I had my opportunity that self-same minute, for, just as I was
going down the garden there to where my husband was doing a little
cabbage-planting, he came into his front verandah. He took the letter
from the postman, and as he looked at the envelope, I saw him give a
start of surprise. His face was as white as death when he opened it, and
he had no sooner glanced at it than he gave a sort of stagger, and if it
hadn't been for the verandah-rail I believe he'd have fallen. He was so
taken aback that I thought he was going to faint. I was standing where
you may be now, and I called out to him to know whether I could do
anything for him. I
