4/18/14 ** I've been reading this series since the third book and since late March. I found that the plot dragged a bit in both this and in Roses are Red - I kept reading though, because I wanted to find out what happened in plot threads in Cross's life (Mastermind, Christine).
The end of this book seemed to resolve both those threads. I wonder if Patterson was considering ending the series. I seem to be hooked though, because I downloaded the next two books to my eReader.
