Ordinary Thunderstorms

Ordinary Thunderstorms by William Boyd started out well. A young man, Adam Kindred, returns to London and inadvertently becomes involved in the murder of a pharmacist developing a new drug. He changes his identity and goes "underground" to try and clear his name while he is sought by the police and others. There are a number of good twists and turns along the way, but I found the ending too incredible and unsatisfying. 31/2/5
