A high-stakes teen mystery of danger, deception, and long-lost gangster loot — perfect for fans of The Hardy Boys, YA crime thrillers, and classic pulp adventures. Seventeen-year-old identical twins Dan and Paul Case think they’re doing a good deed when they pick up a lone hitchhiker. But this stranger is no ordinary traveler. Eddie Ridgway — ex-accountant for a notorious Prohibition-era gangster — has just been released from prison and is rumored to know the location of a fortune in stolen cash. Before the twins can decide whether to believe him, they’re pulled into a dangerous chase involving two ruthless ex-gang members, Wilbur and Gimpy Dalton, who think the brothers are part of Ridgway’s scheme. It's a trail of clues leading to a hidden treasure worth killing for. From backroads stakeouts to heart-pounding escapes, Dan and Paul must outwit seasoned criminals, survive relentless pursuit, and unravel secrets that could change their lives forever. Packed with vintage gangster vibes, modern pacing, and an addictive treasure-hunt plot, The Cash Cache Mystery is a page-turning YA adventure for teen readers, reluctant readers, and nostalgic fans alike. First in the Case Twins Adventure series — standalone novels featuring continuing characters and nonstop action. Rockwood's young adult mystery is a fast-paced tale of suspense and intrigue. The story takes place in 1948, and Rockwood does an excellent job creating the long-ago era with the setting of soda fountains, movie theaters that once aired cartoons before the feature presentation, bridge parties, and '40s slang. Dan and Paul are two likable main characters who resemble the Hardy Boys with a slightly more hard-boiled twist. They aren't afraid to run into danger even when guns and blazing fires are involved. Readers gain inside knowledge on why Dan and Paul are so involved in fighting local crime: the boys were taught by their late father, who died in World War II, and their mother about right and wrong because of their own dark past. In the end, readers will enjoy the sly humor, the brotherly bond between Dan and Paul, and the clever plot. Recommended. - K. Haulotte, US Review of Books - With two endearing young adult characters that were sure to win my heart, Dorian Rockwood crafted a gripping tale in The Silent Witness Mystery . It was a roller coaster ride of adventure, action, mystery, and humor, and I could not put it down. This page-turner had me hooked from the start until the end. With all the twists and turns, I was guessing until the end, and the suspense kept me on the edge of my seat. The characters were well-developed and relatable. Dan and Paul's banter was far from distracting and showed that they had a very good relationship. Despite making some dangerous choices during their investigation, Dan and Paul were set on achieving their goal. This story was beautifully written and a pleasure to read. - A. Boucher, Readers' Favorite - This second installment of the Case Twins Adventures is pitched as a Teen & Young Adult book. Well, I'm an old adult, and I thought it was just peachy... In the final couple of chapters, by which time we've grown to care about these kids, the tension is really cranked up. We can all imagine the creeping dread of being trapped in a sinister place with the bad guys closing in. Rockwood is clever enough to make it a big sinister place, so we spend a couple of chapters biting our nails, wondering how it's going to turn out. Some readers may not gravitate toward the vanilla flavor of this endeavor - there is no hint of today's complex, multi-hued society in Farmingford. But readers willing to overlook that will find a well-written story, both in plotting and mechanics in "The Silent Witness Mystery" by Dorian Rockwood. If you're looking for a quick vacation from cynicism or simply a great teen read, this will be just swell, by golly. - J. Gaynor, Reader Views Kids - Get ready to become addicted! The Silent Witness Mystery is fast paced, with a plot that grabs your attention, cliffhangers that quicken your pulse, and humor that lightens the mood... By each turn of the page, clues are revealed, and suspects are unveiled, but just when you think you have it all figured out, Rockwood throws in a few misdirections to keep you guessing until the very end. With nail-biting action and a cast of unforgettable characters like Ricco and Vinnie, this book is a must-read for fans of small town mysteries and thrilling suspense. And with this being the second book in the series, you will want to keep the author motivated and read the whole series! - grammy2023, LitPick
