Ok I think I screwed up my example... THIS IS A SPOILER ALERT FOR PROFESSOR LAYTON GAME...
Somebody ate the butcher's sausages! Here's
what these four boys have to say:
A: "B ate the sausages!"
B: "D ate them all up!"
C: "I didn't eat them, no way!"
D: "B's totally lying!"
Only #rone of these rascals is telling the truth#x
and all the others are, needless to say, lying.
Can you figure out #rwho ate the sausages#x?

hint 1
Remember, you want to find the person who
ate the sausages, not the people who are
lying.
To attack problems like these, go through
your list of potential thieves, assume that
each one is guilty, and see which statements
fit in each case.
That should get you started. Good luck!
hint 2
If you have chosen the right person, then
three of the four boys' statements should be
false. If you think you've found the culprit,
but only two of the four boys' statements
turn out to be lies, you haven't found the
thief yet.
Here's another valuable piece of information:
only one person ate the sausages.
hint 3
All right, after this hint, you'll probably be
able to guess the answer without thinking,
but here we go.
A and B are lying.
Keep that information in mind and you should
have your answer in no time.
Show solution
C ate the sausages, and the only person
telling the truth here is D.
If you assume A to be the culprit, both C's
and D's statements must be correct.
Choose B, and the other three boys'
statements must be true. If you make D
out to be the criminal, then what both B
and C are saying must be true.
None of these possibilities fit the conditions
set forth in the puzzle.
