I suspect that anyone who has ever taken a creative writing course has been told to write about things that are familiar to them.
I don’t know if Mark Chamberlain ever attended such a class, but if he did he would not have found that advice in the least restrictive.
Mark knows more than most about life; his CV includes stints as a truck driver, a fisherman, a dishwasher, a probation office, a drain digger, a poker machine attendant, a drug and alcohol abuse counsellor, a teacher, and, apparently, one night as a bouncer.
He’s sailed the high seas, he’s tasted good and evil (as Kris Kristofferson would say), and he’s written. Historical fiction, novels (for adults and boys), short stories, text books and more have brought him popular and critical acclaim. And now he’s added to his repertoire with a whodunnit.
