A body in the library

THE LIBRARY has a body on the floor ("OH GOLLY! HE IS DEAD!"), a roaring fireplace that burns Seymour, and a few small things lying about.
Nudge 1Where to look
It's a crime scene. Somebody in a police station wants this solved.
Nudge 2A stronger push
What's lying on the floor here is evidence, and the fireplace guards one of the pieces. Careful how you handle the rest.
Nudge 3Almost there
Read I got arrested! before you pick anything up.

The small things are a marked deck of cards and three dollar pieces. Take the deck only while carrying the rubber gloves (I got arrested!); take a dollar for the case and leave the other two for later (they buy things, and one goes in a slot). The third dollar lies right by the fireplace: walk in, take it, and walk straight out to lose as little energy as possible. Rick Bracy explains what the evidence is for (Rick says there's been a murder).
