Wow! I had no idea that there might be a third book in the Jack Sawyer series. Get on it, Stephen and Peter!
My favorite line from Black House is about "Burnsy's" creepy phone calls and a comment about his weird accent. I don't remember the exact wording, but one guy said something along the lines of "He sounds like a Frenchman trying to speak English with a German accent."
"Burnsey" sounds like he could have come from Saskatchewan. We do have quite the ethnic mix here. For example, back in the 1980s, I went to a wedding with a German bride, Chinese groom and Ukrainian food. In Regina, we have an Irish-style pub co-owned by a Greek guy.
