All Hallows' Eve

All Hallow's eve is the 15 Case in the game.

Introduction
Your friend Jacob has disappeared in the City of Shadows without a trace. The Conductor helps you in your search. His Locating Device shows that Jacob is still alive but is somewhere in the centre of the City. The way to the centre of the City has been shrouded in unearthly fog for many years now. After losing consciousness, you see a vision of Jacob giving you a clue: "Look for the answer in the Collector's House." The Collector is perhaps the most renown and mysterious figure in the City. A man of fortune and foibles, he vanished mysteriously without a trace. The door to his house is adorned with an iron head and it has been locked for a very long time... Just what is hidden behind it?
