Someone borrowed Uncle Logic’s lucky pen.
Exactly ONE suspect is lying.
WHO BORROWED THE PEN?
Clues
- Hailey“June is lying.”
- Mason“Theo borrowed it.”
- June“Mason is telling the truth.”
- Theo“Mason didn’t borrow it.”
Answer
Theo
Why it works
Theo borrowed the pen. Mason, June, and Theo then tell the truth, leaving Hailey as the sole liar.
- Test Theo as the person who borrowed the pen.
- Mason’s statement that Theo borrowed it is true.
- June says Mason is telling the truth, so June’s statement is true as well.
- Theo says Mason did not borrow the pen, which is also true.
- Hailey says June is lying, but June is telling the truth. Hailey is therefore the only liar, so Theo is the answer.
