A Dash of Murder

Food for thought: seasoning with these berries results in a dash of murder.
It's been a quiet autumn so far in the small town of Bradley, North Carolina. Or, as Myrtle would put it, a boring one. The slow pace and lingering post-summer heat are making life in Bradley very slow-paced, indeed.
That all changes when a local resident is poisoned by what looks like a scrumptious pie. The victim is a boorish man who has plenty of enemies in Bradley. Despite this, suspicion falls heavily on Myrtle and Miles's friend-a botanist who grows the deadly nightshade the man was poisoned with.
Can Myrtle and Miles solve the case and help their friend before the killer strikes again?
