Old City Hall by Robert Rotenberg

Kevin Brace is considered the "voice of Canada" because of his radio program that is broadcast across the country. When he's arrested for killing his girlfriend, the case is big news. Brace hires lawyer Nancy Parish to defend him, but this is proving difficult for Parish because he refuses to talk to her, communicating only through the written word. Albert Fernandez is the prosecutor on his first murder trial, working with homicide detectives Ari Greene and Daniel Kennicott to get a guilty verdict. In this first novel, Rotenberg takes the reader from the crime through the trial with a wide cast of interesting characters. He also gives loads of detail about the city of Toronto, so that it becomes a character itself. A great legal fiction debut.
