7th Heaven by James Patterson (Hardcover, 2008)

A city in flames and a trail gone cold . . .

A string of fatal arson attacks has broken out in San Francisco. The targets have one thing in common: they are all rich, successful, married couples. With four couples dead, Detective Lindsay Boxer is determined to put an end to the killings.

When a devastating new lead emerges in the high-profile disappearance of the governor's son, Lindsay suspects the two cases may be connected.

Pushed to their breaking points, can the Women's Murder Club stop the cold-blooded killers before the city burns?
