film disrupted in Toronto

His retired bass, now adviser on an action movie about a former Nazi being hunted down in Toronto. calls in Salter after there is a string of sabotage events that is putting the filming behind schedule. While Salter investigates, one of the actors is murdered. The odd part is that the sabotage seems to be done by someone who must be involved in making the movie, but all those people will lose money if it got delayed. On the other hand, Salter wonders if a genuine ex-Nazi might be around who finds the movie's plot uncomfortable, but how would an ex-Nazi have inside knowledge of the filming? ( )
