'A' is For Alibi, by Sue Grafton

Private investigator, Kinsey Millhone, investigates the murder of a man named Laurence Fife. Nikki, his wife, has just served an 8 year sentence in prison for the murder, but when she gets out she hires Kinsey to find out who the real killer is. Kinsey meets with several people who were close to Laurence Fife at the time of his murder, including his ex-wife and his former law partner, Charlie Scorsoni. This book is fast-paced and keeps you guessing throughout. I will definitely read more from this alphabet series of mysteries by Sue Grafton.
