Five Children and It2004

Martha:
In the morning, I'll give you a tour of the grounds. You're allowed everywhere except the greenhouse. That's strictly off limits.

Jane:
Why would a greenhouse be off limits?

Anthea:
Maybe the plants are deadly, like in "The Black Rose Of Devil's Island".

Jane:
Maybe.

Martha:
The greenhouse is off limits because I said it is. So just stay out of it, and everything will be fine. Here we go. [hums]
