Boston attorney Brady Coyne has a practice that's devoted almost exclusively to meeting the needs of a small group of very wealthy and, for the most part, elderly clients. He's rarely ever in a courtroom and does not do criminal defense work. But when a Vietnam vet is arrested for trafficking in marijuana, a mutual friend reaches out and Brady agrees to step in.
The vet, Daniel McCloud, is a former Green Beret who is suffering the after-effects of exposure to Agent Orange. Marijuana is the only thing that works to relieve the pain and McCloud is growing a small crop at his home in rural New England. Mostly it's for his own use, although he shares a small amount with a couple of other vets in similar circumstances. But the local cops aren't interested in his condition or his explanations. They arrest McCloud, throw him in jail, and confiscate his crop.
Brady agrees to represent McCloud as a favor to a friend, but he warns McCloud that the case is pretty cut and dried: He's in violation of the law, and he's almost certainly going to do time. But then, mysteriously, the case is dropped and McCloud is freed. There's no logical explanation for this, but you don't look a gift horse in the mouth. In the wake of the case, McCloud and Brady become friends, and Brady visits McCloud and his girlfriend on several occasions. Then McCloud tells Brady that he's written a book and would like Brady to find an agent for it.
Brady cannot read the book, and McCloud won't tell him anything about it, which makes the job a lot more difficult, but Brady finds an agent who begins reading the book and who is initially very excited about it. Shortly, though, the agent rejects the book and warns Brady away from the book and from his new friend, McCloud. Almost immediately thereafter, people begin to die and Brady finds himself in the middle of a very confusing and dangerous situation.
Any sensible person would think to leave well enough alone, but Brady is determined to follow this case to its conclusion, no matter the risk, and before this is over, he'll need all of his considerable skills to save himself from joining the list of the recently departed. As always, along the way, his love life will get increasingly complicated, and all in all, this is another very good addition to this series.
