For years, TV writer Patrick Tarr has been writing scripts for shows like “Murdoch Mysteries,” “Cardinal” and “Saving Hope” — but his dream was always to write a book. Now, that dream has become a reality. Patrick’s debut novel, “The Guest Children,” is a chilling supernatural tale inspired by real-life history: the evacuation of 6,000 British children to Canada during the Second World War. He joins guest host Gill Deacon to talk about reframing these events as a ghost story.
