Dr. Jones kept an antique clock in his office waiting room. One day after lunch he had only four patients. When he had returned from lunch the clock was still in the waiting room, but after the fourth patient left and Dr. Jones passed through the waiting room again, he noticed the clock was missing.

The police questioned the four afternoon patients, but they had gotten together and decided that every statement they would make would be a lie.

Adam said: None of us stole the clock. The clock was still there when I arrived.
Bert said: I arrived second. The clock was missing when I arrived.
Charlie said: I arrived third. The clock was still there when I left.
David said: The clock was missing when I arrived.

In what order did the patients arrive, and who stole Dr. Jones' clock?

If they all lied that means:

Adam was not last - Clock was missing when he arrived

Bert was not 2nd   - Clock was there when he arrived

Charlie was not 3rd - Clock was missing when he left

David was not first - There when he arrived

Just sort the responses

Name                    Arrived State          Left State

Bert                       There                       Don't Know

David                     There                       Don't Know

Adam                     Missing                     Don't Know

Charlie                   Don't Know               Missing

David took the clock.
