I remember a trick I used to have I believe it was called Detectives. You had a choice of being Sherlock Holmes or a French Detective (Poirot?) and each had their own card with their picture on it. Anyway I remember it came with a cassette tape explaining the effect which was basically self working. Your spectator would select a card but they would lie to you and the cards would tell you whether they were lying or telling the truth. I've since looked for it but haven't been able to find it. I'm guessing its out of print. Anyone know of this effect?

Never heard of the trick, but it sounds interesting just based on the characters involved. I like both Sherlock Holmes and Poirot. I'll be interested to see the answer. BTW, Poirot is Belgian (I only tell you because people are always calling him French and he always corrects them).

I am sure I have it somewhere around my house just have to dig around for it. It really is a cool trick. With all the historians and gurus on here I'm sure someone has run across it! I'll update the post if I find it.

Believe it or not, I just found it and even found a link for it online. Now I'll have to see if I can find a cassette player to hear the instructions!
