Poison in the Pastry — Laura Pauling

Three famous mystery authors visit Holly's town. One of them never leaves. Is it murder? While sleuthing, Holly juggles her relationship with Trent and good old-fashioned blackmail. Millicent dug into Holly's past and has a long list of demands. Holly worries her past will be exposed and her cover blown. She gives in to Millicent's random demands, even heading undercover on a rogue investigation. But then, Millicent goes too far and demands Holly break up with Trent. More secrets simmer beneath the surface than just the authors' pen names. When Millicent lands in jail, Holly faces the moral decision of helping her frenemy or celebrating. Behind it all, someone's playing twisted games.
