Vices of My Blood by Maureen Jennings
In late 19th Century Toronto a Presbyterian minister is brutally murdered in his office. Detective Murdoch (a Catholic) is in charge of the investigation. It looks like a burglar committed the crime, but the minister, as a volunter for the House of Industry, was responsible for visiting the homes of people who applied for charitable relief and decding which of those were deserving of assistance. Perhaps the murder was an act of revenge.
As a bit of light relief I am also reading Inside Out- A Personal History of Pink Floyd by Nick Mason.
