 The Millennium Group is screening a new candidate, Jim Horn, whom Frank teams up with to investigate the brutal murder of a meter maid. Jim shows promise, but he is also under much of the same stresses that Frank suffered from when he had his nervous breakdown, on top of which Jim s wife has left him and taken their son. Meanwhile, the killer strikes again, slaughtering a postal worker and a nurse, all the while leaving minute messages taunting the authorities. As he tries to prevent another victim from being killed, Frank must also try to keep Jim s growing inability to hold himself together from unraveling the investigation.
