**Fools die on Friday**: If you can add 2 and 2 (and get 4) you can solve this case. It's that simple.
It's so simple, in fact, that even the cops can handle it.
First you're tipped off that a Mr. B. will be poisoned, spoon-fed by his "adoring" wife.
Next, he is poisoned.
Then, the lady vanishes, and it all adds up.
But there's one bit that doesn't add up. The vanished wife was in the house when her husband swallowed the stuff, and a top-drawer detective who was watching the house every second swears she never left. But she did, without a trace.
It's simple.
You figure it out.
