Promoter Harris Crown is killed when the car he is driving goes off a cliff. Burke soon discovers that all the brake fluid had been drained and that the car belonged to Crown's wife (a race car enthusiast) who is involved in a charity benefit and ""involved"" with the benefit's choreographer, who in turn is being kept by a wealthy (and jealous) society matron. Other suspects include Crown's strapped-for-cash brother and his greedy wife, and Crown's current mistress. Burke is assisted in his search for the killer by a gossip columnist and a shop owner (who takes a sudden shine to Burke, until she finds that he's a ""poor"" cop). (thetvdb.com)
