Gray as Ashes - Biscuit McKee Mysteries, #7

Martinsville, Georgia has always been a sleepy little town, where nothing much ever happens, except a few murders... There's a firebug in Martinsville. Town librarian Biscuit McKee isn't too worried when a garbage bin at the grocery store is set on fire. But when it's her beloved garden shed that goes up in flames, the fur begins to fly. Biscuit's feline companion Marmalade comments frequently, ...
Yes, I do.... (even though her humans think she's only purring ... Mouse droppings!... or sneezing). She's as baffled by all this as her humans. We could have some tuna. That would solve a lot. Distracted by a visit from Peachie, an old college friend, Biscuit pays only scant attention to a third fire, but it's hard to ignore the dead body found in the charred remains of Connie Cartwright's studio, where glass-blowing may have turned into homicide.
