Alas all was not well at 52 Festive Road. Mr and Mrs Benn, and their grown up children Bill and Belle were having a deadly row! One of these four people murdered one of the others, one of the Benn family witnessed the crime, and another helped the murderer.
We are certain only of the following:
- The youngest person and the victim were not the same sex.
- The one who helped the murderer was older than the victim.
- The murderer was not the youngest member of the family.
- Mr Benn (the father) was the oldest member of the family.
- The oldest person and the witness were not the same sex.
- The witness and the one who helped the murderer were not the same sex.
So the question is – who was the murderer?
- We know from (1) that the youngest person was not the victim
- We know from (2) that the youngest person was not the helper
- And we know from (3) that the youngest person was not the murderer, therefore we know that the witness was either Bill or Belle (the children).
- We know from (4) and (5) that the witness cannot have been male, therefore the witness (and the youngest person) must have been the daughter.
- We know from (1) that the victim therefore must be male, and from (2) that the helper was older than the victim. Therefore we can deduce that the victim was Bill.
- We know from (6) that the helper must have been male (because Belle is the witness). Therefore because we have already shown that Bill is the victim, the helper can only be Mr Benn.
- That leaves the murderer as Mrs Benn.
