The Wedding

What should have been a simple task, watching your old flatmate Malcolm get married, becomes an awful lot more complicated when it transpires that Malcolm has disappeared mere hours before the service. You are called in by one of the bride's aunts to sort out the problem. But how can you help? Perhaps the answer to the problem lies somewhere within D'Arcy manor, the bride's family home. The odd characters within may be able to help you. First things first, though - how do you get past the nasty security guard?
