Dear sir/madame,
I've recently come accross the knowledge that one of your employees has come into or has been in the posession of the effects of a member of the Dirty Nancies. I may be inclined to purchase some items in this equipment, possibly even the equipment as a whole.
Please drop me a note (right here) with the name of the one who has these effects so we can get into business.
Sincerely,
N
