A terrible crime has been committed and the police round up the usual suspects. During the interrogation of the four men the following accusations and statements are made:

Anderson said "Brimmers did it."
Brimmers said "Dodge did it."
Carter said "I didn't do it."
Dodge said "Brimmers lied when he said I did it."

If only one of the four men was untruthful, which man committed the crime?

If A did it, A and B are both lying, so A is innocent.

If B did it, only B is lying.  B could be guilty.

If C did it, A, B, and C are lying, so C is innocent.

If D did it, A and D are both lying, so D is innocent.

Conclusion: B is guilty, and a liar.
