5/series. I love Flavia deLuce, quirky (to put it mildly) pre-adolescent heroine and sleuth of this marvelous series. This time the organist at St. Tancred's Church is found dead in the crypt where the venerable saint's bones are scheduled to be exhumed. Flavia, of course, is front and center, and notes that the victim is wearing a World War II gas mask. When she falls into an open grave, things get really interesting. The old adage that all crime has a previous crime connected to it is true with this delightful almost-cozy. Flavia, chemist extraordinaire, decodes blood samples, concocts her own much-needed drycleaning solvent, and boils eggs a la Flavia in her fabulous laboratory. Read these in order. Start with award-winning The Sweetness at the Bottom of the Pie. They are worth every moment of your time. It's a 5; they're all 5s.And they'd make great presents.
