Don't forget 'The Beckoning Shadow' - that scared the Hell out of me ...!
The one with a young Edward Woodward (either 'The Listner' or 'The watcher')
'The Tell Tale Heart' was spooky too
one where David Buck kept seeing the long dead corpse of a old man - later he discovers the dead man sat at a insect covered table in a forgotten room (anyone know the title ?)
'Casting the Runes' was spooky and 'Lost Hearts' with the scary 'noise from across the lake' and the conclusion of the torn out heart on the fire was memorable....
is my memory correct ? - in 'Room 13' where David Buck looks out the window of his room & on the wall of the building opposite he sees the reflection of the room 13 that should be part of his large room - in it he can see the silouette of a demonic little 'Goblin' figure is doing a manic dance ....
at the end they find satanic verse & items in the 'wall' between rooms 12 and 14...the wall of 'room 13'
BBC did a colour remake years later that was about as frightening as an episode of 'Hector's House' !
I found, even at the time they were shown on ITV, that the later colour 'Tales of Mystery & Imagination' were an insipid pale shadow of the earlier b/w ones (those mostly now lost)
