Private: No. 1 Suspect is the second book of the Jack Morgan series. This novel was written by James Patterson and Maxine Paetro.
This book has several plots. The most important one involves Jack Morgan, the owner of Private, a private investigation company started by his father. Morgan comes back from a trip to find a former girlfriend murdered in his bed.
Morgan is the number one suspect of this murder and has to clear himself of it or go to a lengthy trial. Morgan also owes a favor to a mobster, a favor he does not want to honor but is in no position to refuse. A third plot is the disappearance of a film star who is already in much legal trouble.
Finally, Private seeks to solve a series of hotel murders that are the work of a serial killer.
