From the Casebook of Nick Velvet (1986)

"Why is this man smiling? He's got charm, sophistication, poise, and people are begging him to steal for them. But why steal such worthless bagatelles as an empty sugar packet or a juggling pin? For the challenge, for the adventure and, of course, for the money." This book contains 4 new cases for use with Ellery Queen's Mystery Magazine Game. According to the cover, they are suitable for solitaire, co-operative, or competitive play.
