Halloween Game: 5 Days a Stranger

LINK The Story [Get in, get the loot, get out... that's how it usually goes for master cat burglar Trilby. But after he breaks into the supposedly vacated country manor erstwhile of the aristocratic DeFoe family, he quickly finds that things are not that simple. Together with a group of strangers, he finds himself imprisoned by some invisible intelligence. A force prepared to do anything to keep them there. Up to and including murder... As the killings begin and suspicion threatens to tear the group apart, it's up to Trilby to unite his squabbling companions and destroy the supernatural entity that victimises them. But what exactly is it? What is the dark secret attached to DeFoe Manor? And what is the significance of the masked maniac who haunts their dreams?].
