Former NYPD deputy commissioner Daley must have taken lots of notes before he retired to write such powerful thrillers as Prince of the City, To Kill A Cop and Wall of Brass. His portraits of police officers cracking under political pressure are absorbing and totally believable, and his latest adds a touch of exotic romance on the French Riviera. Ex-New York detective Jack Dilger and former Nice inspector Madeline Leclerq are both out of work because they crossed the wrong superiors, so it's not surprising that they wind up in danger as well as in bed.
