The scene
Drama School · Interrogation rehearsalA mask disappears as part of an improvisation exam. Only one of the three students knows where they hid it, but all three must answer under a rule supervised by their teacher.
All six statements have been transcribed in full. You do not need to guess at gestures or interpret irony: try each person as the culprit and check whether every answer follows the exercise's rule.
What we know for certain
Exactly one person hid the mask. That person makes one true statement and one false statement. The other two each make two true statements. The statements refer only to who hid the mask, and everyone followed the rule.
The three accounts
Teresa Roig
Acting student«First: Bruno hid it. Second: Celia did not hide it.»
Bruno Ferrer
Acting student«First: Teresa or Celia hid it; one of the two. Second: I did not hide it.»
Celia Mar
Acting student«First: I did not hide it. Second: Teresa hid it.»
Examine the evidence
0 of 5 openedOpening these five clues does not cost points.
01The culprit's rule
Whoever hid the mask must have exactly one truth among their two statements. Two truths or two lies would break the requirements of their role.
02The others' rule
Each innocent person must have two truths. It is not enough for one statement to be true and the other merely plausible.
03Bruno's alternative
His first statement means that either Teresa or Celia is responsible. It does not imply they acted together; the initial rule allows only one culprit.
04What the statements mean
'I' always refers to the speaker. 'Did not hide it' denies responsibility, without saying anything about who may have seen the mask afterwards.
05The teacher's check
The teacher confirms there were no acting mistakes: one assignment satisfies the rules for all three people simultaneously.
