In Thistlecroft, some secrets are buried beneath the blooms...

When dedicated florist Clara Bloomfield is called to refresh arrangements at a botanical symposium, she never expects to find the guest of honor—renowned botanist Dr. Felix Rowan—dead at his desk. The cause? A lethal injection derived from the very rare plants he was studying.

As Clara's floral expertise draws her into the investigation, she uncovers a tangled root system of motives: Dr. Rowan's groundbreaking research on cancer-fighting plant compounds had caught the attention of pharmaceutical giant PharmaTech. But was their interest purely medicinal, or did they have darker applications in mind?

Working alongside the exasperated but grudgingly impressed Detective Nolan Merritt, Clara follows a trail of evidence through research labs, corporate boardrooms, and hidden greenhouses. With a killer willing to silence anyone who threatens their plans, Clara must use her knowledge of plants—both beautiful and deadly—to unravel the mystery before she becomes the next victim.

In this sixth and final installment of the Clara Bloomfield Mystery series, the amateur sleuth with a green thumb proves once again that in Thistlecroft, justice blooms in unexpected places.

"Where botanical science meets murder, only a florist can extract the truth."
