I really enjoyed the Historian by Elizabeth Kostova, incredibly atmospheric although it was admittedly too long by about 200 pages and a bit overwritten at times ! Also like some of Susan Hill's stories like the Small Hand (great story but the channel 5 remake of it was appalling), Man in the Picture and the Mist in the Mirror. Tried the Michelle Paver one set in the arctic on the basis of recommendations here, like a bit of m r james too.
Now the nights are drawing in I'm looking for something in a similar vein so kind of modern gothicky. Any recommendations ?
