The house of brass

"You are invited to a murder." That was how the invitations should have read when aged millionaire Hendrik Brass sent out his messages to six oddly assorted men and women who neither knew him nor each other. All arrived at the isolated Brass mansion, lured by the tantalizing promise of fabulous wealth. But from the moment the shining brass doors of the grotesquely constructed house swung shut behind them, they began to realize they had been enticed into playing parts in a monstrous joke... the joke of a twisted, brilliant mind... a joke whose punch line was murder...
