下一個胡迪尼要揭發的騙局則較為複雜。當時的人們會舉行召靈大會 (séances：為與死人溝通的超自然聚會) ，而在召靈大會上，死人的靈手會出現並留下指紋。這種型式的騙局又名「採靈魂的指紋」。其實真實情況為召開騙局的人會製造死人的手部模型。然後，當他與死人的親友共同召開召靈大會時，就會出現神祕的模型手指紋 。您何以認為揭發這些騙局對胡迪尼而言很重要呢？


The next kind of fraud that Houdini worked to expose was a little more complicated. At that time, people held séances (spiritual meetings to communicate with the dead) where spiritual hands of dead people would appear and leave fingerprints. This kind of fraud was known as "fingerprinting a spirit." What happened was the person committing the fraud would make a mold of a dead person's hand. Then, during a séance with the dead person's relatives, fingerprints from the hand would mysteriously appear. Why do you think it was important to Houdini to expose this kind of behavior?
