Verse and Vengeance (Magical Bookshop, #4)

With the help of Walt Whitman's works, magical bookshop owner Violet Waverly puts her pedal to the metal to sleuth a bicycle-race murder that tests her mettle.
A bicycle race is not Charming Books proprietor Violet Waverly's idea of a pleasant pastime. But police chief David Rainwater wheelie wants them to enter the Tour de Cascade as a couple, so she reluctantly consents.

The Tour de Cascade is the brainchild of Violet's Grandma Daisy. The race is a fundraiser to build the Cascade Springs Underground Railroad Museum. But not everyone in this Niagara Region village supports the race. As if the bike race weren't tiring enough, pesky private investigator Joel Redding is snooping around Charming Books. It takes all of Violet's and Grandma Daisy's ingenuity to keep Redding from discovering the shop's magical essence--which communicates with Violet through books.

When Redding perishes in an accident during the race, David discovers that the brake line of the private eye's bike was cut. Worse, Violet tops his list of suspects. As Emerson the tuxedo cat and resident crow Faulkner look on, Charming Books steers Violet to the works of Walt Whitman to solve the crime. But no other names ring a bell as culprits, and as David's investigation picks up speed, Violet will have to get in gear to clear her name.
