Silent Prey is a sequel to Eyes of Prey. Michael Bekker, the evil mind in Eyes of Prey, escaped from prison and ran to New York, where he continues torturing and murdering people. Lucas Davenport, who has resigned from police department, is brought to New York as a consultant to help capturing Bekker and to secretly investigate a series of murder by so-called 'Robin Hood', a sort of vigilante force. For Lucas Davenport, New York means Lily Rothenburg, his old flame, but now she already has a fiancé.
In my opinion, Silent Prey is not as good as the previous book, although it was still an enjoyable read.
