Between a Rock and a Hard Place — Marty Wingate

Perfect for fans of M. C. Beaton or Susan Wittig Albert, the Potting Shed Mystery series from bestselling author Marty Wingate heads to Scotland as Pru Parke plans her wedding . . . all while a vengeful murderer is poised to strike again. 
 
After her romantic idyll with the debonair Detective Chief Inspector Christopher Pearse culminates in a marriage proposal, Pru Parke sets about arranging their nuptials while diving into a short-term gig at the Royal Botanic Garden Edinburgh. At hand is the authentication of a journal purportedly penned by eighteenth-century botanist and explorer Archibald Menzies. Compared to the chaos of wedding planning, studying the journal is an agreeable task . . . that is, until a search for a missing cat leads to the discovery of a dead body: One of Pru's colleagues has been conked on the head with a rock and dumped from a bridge into the Water of Leith.
 
Pru can't help wondering if the murder has something to do with the Menzies diary. Is the killer covering up a forgery? Among the police's many suspects are a fallen aristocrat turned furniture maker, Pru's overly solicitous assistant, even Pru herself. Now, in the midst of sheer torture by the likes of flamboyant wedding dress designers and eccentric church organists, Pru must also uncover the work of a sly murderer -- unless this bride wants to walk down the aisle in handcuffs.
