When American expat and bicycle tour company proprietress Sadie Greene guides a hard-to-impress group of sophisticated seniors on a stunning trip in northeastern France, she expects some twists, turns, and sudden stops to sip the Riesling. She doesn’t anticipate a detour leading straight to murder …

Sadie Greene and her Oui Cycle crew vow to wow her most discerning private group yet with a trip they will never forget. It won’t be easy. The Silver Spinners, six globetrotting seniors, arrive with thrilling tales of two-wheeling adventures. Sadie worries she’ll fail to impress such worldly travelers, even with the backdrop of Alsace, a dreamy region of rolling vineyards, delicious cuisine, and fairytale architecture. Sadie is dead wrong. Her group is stunned, but not for the right reasons …

Trouble starts when a guest crashes into a corpse on a solo midnight ride. Or so she says. But when body isn’t found, Sadie hopes it was all a bad dream. She aims to reset the mood with a fun, sunny day pedaling through the vineyards. However, an impromptu detour ends in a crash, and a shattered wine barrel isn’t the only victim. A dead man spills out. Sadie still thinks they can ride away unscathed. After all, who would they know so far from home? Murder once again throws a wrench into Sadie’s gears. The corpse has shocking links to her tour.

The Silver Spinners are key witnesses, prime suspects, and dangerously eager to play amateur detectives. Sadie finds herself tangled in the chaos. With her guests’ lives and Oui Cycle’s reputation on the line, Sadie is determined to trail the culprit. But can she stay on course long enough to reach the truth, or is she heading for a fatal collision with a cunning killer?
