When ex-RAF Police investigator Mike McAllister inherits a sprawling South Australian winery, he’s hoping for rest, routine, and a chance to finally escape the chaos of international intelligence work. But peace proves elusive when a body is discovered on the 16th hole of the local golf course—murdered and eerily marked by an occult card pinned through the eye with a golf divot tool.

Suddenly thrust back into an unofficial investigation, McAllister finds himself entangled with an eclectic cast of locals—Morgan Redfield, a confident and sharp-tongued viticulturist with secrets of her own; Hazel Flynn, a deeply intuitive receptionist with ties to the spirit world; and Banjo Paterson, a loyal friend who’s not above nudging Mike into trouble “for a good cause.”

As the mystery deepens, strange visions, warnings from clairvoyants, and a series of darkly symbolic clues hint at a killer who plays by no earthly rules. The past won't stay buried, and neither will the victims.

McAllister : Conundrum is a richly atmospheric blend of suspense, spiritual insight, and dry Aussie humour. With the Barossa Valley’s vineyard-covered hills and the green, green grass of Wales as its backdrop, the novel weaves together ritualistic murder, inner healing, and the weight of choices that can’t be undone. Mike must confront not only a cunning killer, but also the deeper truths he’s spent a lifetime avoiding.

This isn’t just a whodunit—it’s a journey into what drives us, haunts us, and ultimately, redeems us.

For listeners who enjoy twisty mysteries, layered characters, and a touch of the paranormal, McAllister : Conundrum is as intoxicating as a glass of Barossa red.
