Grandfather Guardian - Anthony W. Eichenlaub - Bog

Seasoned, strange, and dangerously clever
Some invitations are impossible to refuse. When Ajay and Kylie are invited to a dinner party hosted by one of the wealthiest women around, Ajay sees it as an opportunity to dig into her past. He needs to find what shady business she's been up to and how dangerous she really is.
Never mind that she's Kylie's grandmother.
What starts out as a dinner party turns quickly to trouble when a guest is murdered. Was the killer the billionaire socialite, the odd chef, or one of the other guests? Ajay needs to cut through the complex connections between the reluctant guests, because one of them is a killer-but they aren't the only one.
Too old to learn decent manners? Maybe. Too old to solve a murder?
Not this grandfather.
