The Cash Cache Mystery

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.

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.
