The O Line Mystery Shorts books 1 through 11 comprise the complete dramatization of the mystery series of short stories. Originally released as podcasts, they have been remastered for audiobook listening.

Book 10 features the following episodes: 41, "Greed and Loathing"; 42, "Red, White, and Scotch"; 43, "The Elderly Renegades"; and 44, "Trust Building".

Set on Ohlone Island in the San Francisco Bay, island inhabitants Lorna and Annie have a penchant for discovering fraud, corruption, and murder. In episode 41, "Greed and Loathing", Michael and Sally follow their suspects giving Lorna time to think and prepare her own special way. When Michael's suspect turns up dead there is only one conclusion, and thanks to Lorna's preparedness training they lose no time in chasing down their only lead.

Episode 42, "Red, White, and Scotch", is their final push to find Annie's contact. The women end up in a foreign land, slogging through the snow and confusion as Michael directs them via a satellite phone to a bullet-riddled former CIA safe house. But the safe house is where the real chase - through the streets of Prague - begins.

Just when they think it is over, in episode 43, "The Elderly Renegades", there are clandestine services, corporate contractors, and the Russians chasing them and the device, so the women make some snap decisions that could cost another life. After Lorna deploys her diversionary tactics so Annie and Sally can escape to safety, Annie takes a page from Lorna's preparedness lectures and doesn't lose hope and continues to prepare for their next steps. Then in episode 44, "Trust Building", with their trust in one another on shaky ground anyway, Michael, Sally, and Annie are on their way to Virginia to be debriefed. And in Roberta's attempt to build trust again with Lorna, she asks for help in creating an Island Watch and puts Lorna on a police ride along to disastrous results when the police officers have other plans for this ride along.

Following in the footsteps of Classic Radio Dramas, The O Line Mystery Shorts brings to life new stories for the digital age. The companion book series - available exclusively on Kindle e-books - includes an introduction and the scripts that follow the evolution of these stories.
