Digging swimming pools by hand in Key West, Florida, Jack Reacher is as tanned and as fit as he's ever been. A local girl says he looks like a condom filled with walnuts. Being invisible has become a habit. He doesn't want to be found. So when a private detective comes nosing around and asking questions, Reacher is not pleased. Especially when he later finds the guy dead. With his fingertips sliced off. Why was he so determined to find him? What does the vicious Wall Street honcho Hook Hobie have to do with it? And what about the reappearance of a woman from Reacher's own troubled past? "Tripwire" is a taut, nailbiting adventure which once again stars Lee Child's irresistible hero, the maverick former military policeman Jack Reacher.

李·恰尔德，声名如日中天的硬派惊悚小说大师。一九五四年出生于英国，与《魔戒》的作者托尔金读同一所高中，拿同样的奖学金。从法律系毕业后，他曾在一家英国电视公司担任主持人和导演。年届不惑之时他忽然失业，酷爱阅读的他花六块美金买来纸笔，开始动笔写第一本小说，也就是“杰克·雷切尔系列”的首曲——《杀戮之地》。本书一出版即登上英国《泰晤士报》的畅销书排行榜，在美国赢得推理小说最高殊荣之一的安东尼奖，以及马瑞奖的“最佳处女作奖”，而次年出版的第二集《博命一击》亦荣获W.H.史密斯好读奖。

在“杰克·雷切尔系列”中，李·恰尔德塑造的杰克·雷切尔这个当代惊悚小说中最亮眼的人物，被评论家形容为现代的西部英雄，荟萃美国精神的游侠骑士。蓝登书屋集团总裁和美国前总统克林顿都是他的拥趸，称之为“二十一世界的詹姆斯·邦德”。

迄今，“杰克·雷切尔系列”已出版十二本，每一本都将李·恰尔德的成功推向新高，版权已售至43个国家。系列中多部作品的浓缩版权由《读者文摘》买下。派拉蒙影业和汤姆·克鲁斯的制片公司C/W已签下全系列的电影版权。连大师斯蒂芬·金都盛赞：“所有关于杰克·雷切尔的冒险故事都帅呆了！”
