"Death In Slow Motion"
Robin is taken to a lumber yard and tied to a conveyor belt which leads to a very large, very sharp table saw. Riddler puts Robin to sleep with gas and then hits the ON switch. And Batman is nowhere to be seen!
"After many gazzers, here is the real buzzer. Is Robin going to wind up as his own double?"
When Riddler took Robin, he left behind two riddles for Batman. Solving these riddles, the Caped Crusader learns where the Boy Wonder is. At the lumber yard, Batman realizes he is too late! As he stops the saw which has just hit Robin's head, he realizes that things are not as grim as they seem. That's a dummy on the conveyor belt!
Riddler decides to get into pictures.
