Time to call the Hardy Boys or maybe Nancy Drew.
Came in to the office today and found that someone had taken an oak credenza and a wood glass-front bookcase. Gone. Over the weekend, somebody decided they liked the front office furniture, so they came in and took the good stuff (including the book case which I bought a few years ago and cost the company about $800).
We have our cracker jack security folks on it; at the moment they're grilling everyone who key-carded in over the weekend.
I think we ought to call Nancy Drew or Frank & Joe.
