One day, there was a piece of cake meant for Eric. However, it went missing. His parents, Mr and Mrs Tan, suspected that one of his siblings ate the piece of cake and so questioned them. Here were their answers:
Charles: It wasn't Darius. It was Brenda.
Darius: It was Alfred. Or maybe it was Brenda.
Brenda: It wasn't Charles. Neither was it Alfred.
Alfred: It wasn't Brenda. It was Charles.
Each of them made exactly ONE true and ONE false statement. Who ate the piece of cake?
