The leading story on the Table of Contents for On Spec Vol. 1 No 1. tells it all.

“Boy at Heart”, a work of short fiction by Dave Duncan.

His bio note in that issue said:

DAVE DUNCAN lives in Calgary, Alberta. He is the author of the fantasy novels, Shadow, A Rose-Red City, and the epic and quirky Seventh Sword Trilogy. He reports that, for a change of pace, his next two books, West of January, to be released in August, and Strings, due out early next year, are both science fiction. “Boy at Heart” is his first published short story. 

Dave’s prolific writing career began after he retired from his first career as a petroleum geologist. He worked tirelessly, even after suffering some mild strokes in recent years, and more than 60 books bear his name on their covers.

When we were thinking of starting On Spec, we put out a call to our fellow members of Canada’s SF community, asking them to take a chance on this upstart magazine by sending us a story to publish. Dave could have graciously declined the request. He was already widely-known as a novelist, not a short fiction writer. But he sent us a story, nonetheless. We will always be grateful for his trust.

Since Dave’s tragic death, many of his fellow writers have written of their long friendship and professional association with Dave. He was a regular guest at regional SF conventions; he was always happy to give of his time and knowledge; he was always ready to help a writer who needed advice. Dave was probably one of the most generous souls we’ve ever known.

Fare thee well, Dave. You were a fine man to call our own.
