Gerritsen books continue to be among my favorites. This novel follows form as she presents a suspenseful, tight, and fairly believable story of a serial killer who is literally hiding right under the Boston PD's noses. Throw in the main protagonist, Jane Rizzoli, and ties to ancient Chinese martial arts mysteries and this one just seems to flow right off the pages. Gerritsen's strength, I think, is the fact that she makes her characters seem real, people that the reader can identify with. Looking forward to the next Rizzoli/Isles novel.
