Five Moves of Doom is a high-altitude and high-attitude entry in A.J. Devlin's award-winning mystery series, one that finds its hero pushed to his absolute limit, relying on his closest allies to survive, and making choices he never thought he'd have to make.

Hired by local mixed martial arts trainer Elijah Lennox to find a missing UFC Championship belt, pro-wrestler PI "Hammerhead" Jed must extract answers from the tight-knit MMA community.

Still consuming his weight in banana milkshakes, Jed ventures into a world of jewel thieves, bodybuilders, eccentric yoga enthusiasts, and adorable baby goats. As he infiltrates an exclusive and unique no-holds-barred fight club, Jed might just find himself down for the count ...

    “A.J. Devlin does it again with Five Moves of Doom! It’s fast and furious and fun, full of action, unexpected twists and turns, with a shocking ending that proves once again that Devlin is not only on his game, but in a league of his own. The best yet in the ‘Hammerhead’ Jed series.”

    “I ripped through Devlin’s latest. At times I felt I was in an MMA fight with dialogue as dry as a three olive Martini and descriptive prose peppering me with blows and throws. It may be a cliché, but this book’s a knockout.”

    “A.J. Devlin nails it with his explosive, hard-hitting fight scenes. A well-written and entertaining look into the most interesting sport in the world — Mixed Martial Arts — through the eyes of tough guy PI ‘Hammerhead’ Jed!”

    “This time around, ‘Hammerhead’ Jed isn’t the toughest guy on the block, and the adrenaline-pounding excitement when his investigation leads him to square off against a particularly ruthless and brutal MMA fighter brings to mind Rocky vs. Drago. Bigger, badder, and darker, Devlin’s third installment reveals a deeper and more vulnerable side of our favourite wrestler-detective, adding gravitas to a case involving a world where second place often means death.”

    “Five Moves of Doom is a fast-paced, rollicking rip through the vibrant and seedy neighbourhoods of Vancouver and surrounding area. With Devlin’s usual cast of colourful, eclectic characters along with his equally colourful regular cast — including ‘Hammerhead’ Jed, cousin Declan, and VPD Detective Rya Shepard — this adventure took me back to many familiar haunts in Vancouver’s skid row and some of the outlying regions around the city and the Lower Mainland. MMA, murder, mayhem and money make this a can’t miss!”

    “It’s a case of same place, different terrain as Vancouver’s pro-wrestler PI grapples with new threats that force him to confront dark truths about his city and himself. In Five Moves of Doom, Devlin showcases a more vulnerable ‘Hammerhead’ Jed than we’ve seen before. While this installment features the signature comedy and charm of the first two books, it’s the shadows, spilling from corners and pooling at feet, that give this latest mystery its true shape. A worthy cap to this trilogy.”
