Things in Napa Valley are not as they seem. Everyone wants to get into the wine business, but at what cost? When the co-owner of Pavesi Vineyards goes missing there are few clues to his disappearance. When his remains unexpectedly turn up, dark forces loom large. FBI Special Agent Rowan Parks is assigned to the case and quickly realizes that the Bureau needs someone on the inside. There is only one person to call, her former lover, and ATF's greatest undercover operative, David Ward.

Deep Purple Cover is book #4 in the Deep Cover series, following Ward's debut in Deep White Cover, Deep Green Cover and Deep Red Cover.

Praise for the Deep Purple Cover

"Joel W. Barrows' Deep Purple Cover has flavors of mystery and dark motives with fragrant twists. Medium-bodied and knowledgeable of the subject matter, the aroma of the novel is robust in its procedural qualities with just a hint of thriller. Interesting characters also make it perfect for the bookshelf where it will pair nicely with a Baldacci, a Sandford or a Coben. Deep Purple Cover is a truly notable vintage." -Craig Johnson, author of the Walt Longmire Series

"Deep, dark and authentic. Great characters. Great read." -Colin Campbell, author of the Jim Grant thrillers

"Something's rotten in California wine country, as noted by the discovery of a decapitated head floating in a barrel of fine wine. Whether you're a wine connoisseur or not, you'll dig Deep Purple Cover, Joel Barrow's latest twisty, gripping fact-based whodunnit mystery thriller. Watch the sparks fly as FBI agent Rowan Parks hooks up with her former love, AFT undercover agent David Ward, to solve the case." -Charles Salzberg, twice nominated Shamus Award author of Second Story Man and Swann's Last Song

"Barrows proves to be a masterful storyteller with his tale of deadly dealings in the fertile vineyards of Napa Valley." -Stephen Burdick, author of Deemer's Inlet and The Gray Detective

"With a full cast of captivating characters and a zig-zagging plot stuffed full of twists, Deep Purple Cover burns along to its end. Star of the Deep Cover series, undercover agent David Ward travels to a California vineyard to aid in investigating a heinous murder and the layers beneath it. Who knew wine was so bloody?" -Ryan Sayles, Derringer-nominated author of the Richard Dean Buckner hard-boiled PI series
