Harry St. John was always a good kid with a dark streak. Now that he's somewhat grown up, he's a crime writer living in Auckland, New Zealand. Although he has tattoos and facial hair and enjoys telling tales about thieves and gangsters and murderers, he's actually a pretty nice guy.

When he's not writing about bad people doing bad things, Harry's studying toward his Postgraduate Diploma in Forensic Science. And when he's not doing that, you'll find him in a dark corner with his nose in a book. Disturb him if you dare.

Harry also writes urban fantasy, superhero stories and other nonsense under the name Chris Strange.
