Marlon receives a mysterious phone call from his old boss, who sounds badly injured as he begs him for help. It's a blast from his criminal past, and someone he's not spoken to since joining the police force. When Marlon hurries over, he's horrified to find his former boss dead – having been shot. And the only witness is a parrot...Marlon's determined to solve the case, insistent that – although his former boss dabbled in criminality – he wasn't a bad guy. But when the team uncover two potential suspects, they're frustrated to find themselves at a stalemate. Whilst one suspect has every opportunity but absolutely no motive, the other has every motive but a rock-solid alibi.
