Sam's mother can't wait to wed her wealthy beau, Harold Robertson. The big mystery is how they're going to pull off a lavish wedding in three weeks.

Meanwhile, when she's not writing, Sam and her beloved and boisterous Nana Jo rush to shine a light on Lydia's killer-so her mother's new husband won't spend his honeymoon behind bars . . .
