Two weeks after the Central City Bank was robbed, Muggs, Looey, Fingers, and The Hermit were picked up on suspicion of the crime.
During the questioning, Detective I M Cagey managed to get a statement three sentences long from each man.
With the help of a lie detector, Detective Cagey found that each man told only one lie.
So, two sentences in each man's statement contained the truth, and one contained a lie.
(Obviously, if a man indicates that he's innocent in two different sentences, he must be.)
Knowing these facts, Detective Cagey was able to deduce who the guilty person was.
Can You Do The Same?
One statement that each man made must be false.
I Never robbed anyone.
I was in New York that day.
I did not rob the Central City Bank.
I was with Muggs in New York.
I've never been to Central City Bank before.
I am innocent.
Muggs said i did it.
Yes, I was in town all that day.
I was never in Central City Bank, though.
Looey didn't do it.
Muggs wasn't really in New york that day.
I went to New York that day, so i couldn't have done it.
