Hello. I would like to buy some mystery/thriller/horror books.
Something like:
Some guy is missing, and he left strange note. Then his friends go to mysterious journey to find him. Trains, hotels, murders.. stuff like that. But not like Agatha Christie novels, something darker.
Or:
Group of people stranded in creepy Scottish/English village with odd inhabitants and possibly some ancient Celtic ruins nearby.
Are you familiar with any similar book?
I appreciate your help.
