空屋（6）

A minute examination of the circumstances served only to make the case more complex. In the first place, no reason could be given why the young man should have fastened the door upon the inside. There was the possibility that the murderer had done this and had afterwards escaped by the window. The drop was at least twenty feet, however, and a bed of crocuses in full bloom lay beneath. Neither the flowers nor the earth showed any sign of having been disturbed, nor were there any marks upon the narrow strip of grass which separated the house from the road. Apparently, therefore, it was the young man himself who had fastened the door. But how did he come by his death? No one could have climbed up to the window without leaving traces. Suppose a man had fired through the window, it would indeed be a remarkable shot who could with a revolver inflict so deadly a wound. Again, Park Lane is a frequented thoroughfare, and there is a cab-stand within a hundred yards of the house. No one had heard a shot. And yet there was the dead man, and there the revolver bullet, which had mushroomed out, as soft-nosed bullets will, and so inflicted a wound which must have caused instantaneous death. Such were the circumstances of the Park Lane Mystery, which were further complicated by entire absence of motive, since, as I have said, young Adair was not known to have any enemy, and no attempt had been made to remove the money or valuables in the room.

现场的详细检查只是使案情变得更加复杂。第一，举不出理由来说明为什么这个年轻人要从屋里把门插上。这有可能是凶手把门插上了，然后从窗户逃跑。由窗口到地面的距离至少有三十英尺，窗下的花坛里正开满了番红花。可是花丛和地面都不象被人踩过，在房子和街道之间的一块狭长？草地上也没有任何痕迹。因此，很明显是年轻人自己把门插上的。假使有人能用左轮手槍从外面对准窗口放一槍，而且造成这样的致命伤，这人必定是个出色的射手。另外，公园路是一条行人川流不息的大道，离这所房子不到一百码的地方就有马车站。这儿已经打死了人，还有一颗象所有铅头子弹那样射一出后就会开花的左轮子弹和它造成的立刻致死的创伤，但当时却没有人听到槍声。公园路奇案的这些情况，由于找不出动机而变得更加复杂，因为，正如我前面所讲的，没人听说年轻的阿德尔有任何仇人，他屋里的金钱和贵重物品也没人动过。
