Thorns

Shelton believes flowers save people, so Ruth-Anne Grant's demands that he remove her name from his floral delivery list appall him. Because it turns out the roses he spent his morning crafting came from her stalker. Shelton, embarrassed and frightened for her, gives her the stalker's name, thinking his involvement will end there. Only it doesn't. The police show up at his flower shop two days later, and they don't care about a stalker.
They want to catch a murderer. And they need Shelton's help."Kristine Kathryn Rusch's crime stories are exceptional, both in plot and in style."-Mystery Scene Magazine
