Death by vanilla latte
(Book)

Series numeration from Goodreads.

"Ever since café owner Krissy Hancock settled into a relationship and--mostly--forgot about old flames, life has become surprisingly serene. Too bad her father, famed mystery writer James Hancock, had to pay an unexpected visit to Death by Coffee and brew up a batch of trouble . . . While caught off-guard by her dad's presence, Krissy never dreamed he'd become the biggest murder suspect in town. But that's exactly what happens when James's boorish agent--a man he allegedly fired just hours earlier--is found cold and lifeless, a still-warm vanilla latte resting by his hand . . . With Pine Hills divided over her father's innocence and a fanatical fan keen on locking the author away for safe keeping, Krissy must end the madness and identify the real criminal--even if that means meeting an ex or two along the way. But as her social life becomes increasingly chaotic, Krissy may be caught in a case that's far too hot to handle" -- provided by publisher.
