Reader beware - you're in for a scare!
Dr Brewer is doing a little plant-testing in his basement. Nothing to worry about. Harmless, really.
But Margaret and Casey Brewer are worried about their father. Especially when they . . . meet . . . some of the plants he is growing down there.
Then they notice that their father is developing plantlike tendencies. In fact, he is becoming distinctly weedy - and seedy.
Is it just part of their father's "harmless" experiment? Or has the basement turned into another little shop of horrors?
