There is one and only one Dracula
This Dracula is locked in three and only three caskets
One is solid red, one is solid yellow, one is solid blue
The caskets have inscriptions
Red says, Dracula is here (meaning inside the casket)
Yellow says, Dracula is not here (not inside the casket)
Blue says, Dracula is not in the red casket
At most one inscription is true

Where must Dracula be

• Yellow
  As then red and yellow will be false
  and blue true
