Poisoned Petals — Joyce Lavene; Jim Lavene

Meet Peggy Lee: botanist, detective's widow, and owner of The Potting Shed, an urban gardener's paradise in downtown Charlotte. With the beautiful spring weather, business is booming -- and death is in full bloom...

Peggy Lee is just about to deliver some endangered sunflowers to Darmus Appleby when a gas explosion blows out his door -- and Peggy finds her fellow botanist dead on the kitchen floor. And only two weeks later Darmus's brother dies, after being found unconscious in a community garden with his brother's wedding ring in one hand and -- in his pocket -- a lovely purple hyacinth with an overpowering scent.

Now Peggy must follow her nose -- and some cryptic clues from an Internet informant -- to root out a killer before he strikes again...
