The Spiralling Worm is a series of interlinked stories of two government agents fighting the cosmic horros and alien monsters that Lovecraft created. David said, "One aspect of The Spiralling Worm that I'm proud of is that my protagonist, Major Harrison Peel, is a Royal Australian Army intelligence Officer, transposed into a gloal setting. Chaosium were very suppostive of keeping him as an Australian character, when they could so easily adapted him as an American character."
David has been making a name for himself recently with his science fiction and horror writing, being nominated for Aurealis and Ditmar awards. A recent science fiction story has been nominated for the Irish Aeon Awards.
