The Accident by Linwood Barclay

Contractor Glen Garber gets worried one evening when his wife, Sheila, hasn't come home yet from the business class she's been taking in the hopes of landing a high-paying job. He is stunned when the police tell him that Sheila caused an accident while driving drunk that took her life and two others. Left to be the sole parent to their 8-year-old daughter, Kelly, Glen is bereft and flummoxed because he never knew Sheila to be a reckless driver. When a friend of Sheila's is found dead and the police find her death suspicious, Glen tries to make sense of what's going on, but finds only more questions and people evading the truth. He also finds his life turning into an emotional and financial nightmare. In The Accident, Barclay has written another thriller that explores the dark underbelly of domestic suburbia. Suggested for people who like Harlan Coben.
