Kill Alex Cross

This is an okay book written by James Patterson. Detective Alex Cross is one of the first on the scene of the biggest case he's ever been part of. The President's son and daughter have been abducted from their school – an impossible crime, but somehow the kidnapper has done it. Alex does everything he can but is shunted to the fringes of the investigation. Someone powerful doesn’t want him too close. A deadly contagion in the DC water supply endangers the capital, and Alex sees the looming threat of the most devastating attack the United States has ever experienced. He is already working flat out on the abduction, and this massive assault pushes him completely over the edge.

This is the 18th novel in the series.
