海军协定（15）

“How about the fireplace?”

“They use none. There is a stove. The bell-rope hangs from the wire just to the right of my desk. Whoever rang it must have come right up to the desk to do it. But why should any criminal wish to ring the bell? It is a most insoluble mystery.”

“Certainly the incident was unusual. What were your next steps? You examined the room, I presume, to see if the intruder had left any traces—any cigar-end or dropped glove or hairpin¹ or other trifle?”

“There was nothing of the sort.”

“No smell?”

“Well, we never thought of that.”

“Ah, a scent² of tobacco would have been worth a great deal to us in such an investigation³.”

“I never smoke myself, so I think I should have observed it if there had been any smell of tobacco. There was absolutely no clue of any kind. The only tangible⁴ fact was that the commissionaire's wife—Mrs. Tangey was the name—had hurried out of the place. He could give no explanation save that it was about the time when the woman always went home. The policeman and I agreed that our best plan would be to seize the woman before she could get rid of the papers, presuming that she had them.

“壁炉的情况怎么样呢？”

“那里没有壁炉，只有一个火炉。电铃正在我写字台的右首。谁要按铃都必须到我写字台右首去按。可是为什么罪犯要去按铃呢？这是一个最难解释的疑一团一。”

“这件事确实非同寻常。你们的下一步措施是什么呢？我想，你们检查过房间，看看那位不速之客有没有留下什么痕迹，象烟蒂、失落的手套、发夹或其它什么小东西，是吗？”

“没有这一类东西。”

“没有闻到什么气味吗？”

“唉，我们没有想到这一点。”

“啊，在调查这样的案件时，即使有一点烟草气味对我们也是很有价值的。”

“我一向不吸烟，我想，只要屋里有一点烟味，我就会闻出来的。可是那里一点烟味也没有。唯一确凿的事实就是看门人的妻子，那个叫坦盖太太的女人，是从那地方慌忙走出来的，看门人对这件事实也无法解释，他只是说他妻子平常就是在这个时间回家。警察和我一致认为，如果文件确实在那个女人手里，那我们最好趁她没把文件脱手就把她抓住。
