This note contains spoilers for the book.

A Holly Barker novel. Same universe as the Stone Barrington books, and she's in some of them, but he's not in this one of hers.

Really kind of slipshod. Things like a safe whose combination is numeric at one point and alphabetic at another (to allow a side character a parting shot).

I don't believe in the high-speed brute force electronic lock-pick, either. My safe's electronic lock locks for a while after seeing too many failures in a short time, but Teddy's much more expensive safe apparently doesn't. It's the obvious precaution, used in computer security all the time.

However, the characters finding new loves seem to be pairing off happily, at least (though one of them is with a possibly-retired serial killer).

The title seems to have no connection to the book. No orchid or even flower theme, and no apparent reference for the colloquial meaning (not strong enough for the real world). I think some of the other Barker books use "orchid", so possibly it's just a reference to this one taking place in Florida where it's hot.

Lots of back-story threads. Someone who Holly was in the Army with turns up, and the Colonel who commanded them and tried to rape them and got court-martialed and thrown out. Now he's shown up to be Chief of Police in the town Holly's Florida house is near (she was chief in that town herself for a while at one point, so she knows most of the officers).
