《林中异形》是一部40年代风格的科幻小说，其中的女主角是个作家，发现了埋在土中的一架外星飞行器。

In the spring and summer of 1986 I wrote The Tommyknockers, often working until midnight with my heart running at a hundred and thirty beats a minute and cotton swabs stuck up my nose to stem the coke-induced bleeding.

1986年春夏，我写《林中异形》（小说原名为TheTommyknockers，典出美国传说，死去的矿工魂灵会变成Tommyknockers，敲打矿壁告诉采矿的工人矿石埋藏地或者提醒他们暗藏的事故危险），经常工作到半夜，心脏狂跳到每分钟一百三十次，鼻子里塞着棉球，堵住因为吸食可卡因导致的流血。
