I will try to prevent my adoration of the brilliant Hugh Laurie affect my review of his first (and, to date, only) published novel, but I will admit that it was the only reason I was initially interested in reading The Gun Seller. While the book itself might not be expressly profound or lasting, it's great for some light reading (or airplane reading, as it was for me).
Overall, this spy-genre spoof is great fun. If you are familiar with Laurie's days before the successful show House, MD then you are aware that he knows a thing or two about comedy (that dry, weird Brit comedy). This book is dripping with humor of that sort. Know him as Dr. Greg House? There's a bit of that scathing sarcasm in The Gun Seller, too. You can't help but picture Laurie himself as Thomas Lang, the protagonist of the story. I think that only makes the book more enjoyable.
The plot itself is a little over-the-top with conspiracies, terrorists, arms dealers, a damsel in distress and, of course, motorcycles (again, if you know anything about Laurie). But then again, what spy/action plot isn't a bit far-fetched and fantastic (i.e., James Bond). Like the Bond character, I can envision the character of Tom Lang being serialized and continuing in a series past this book. We learn enough about the character's history and personality (and that of his quirky Jeeves-like colleague, Solomon), to make him a lasting character.
I can't say I'm an expert on spy novels (or their spoofs), but I do think this offering from Laurie is worthy of a read for fans of the genre, or for those appreciative of intelligent, dry humor.
