I really liked it...love a proper spooky mystery. Especially with some good old fashioned jump scares!
Maybe the Indian lady is/was his nanny/ayah who became possessive and jealous of other women in his life? Murdered (drowned?) his mother, maybe a girlfriend (in the sea at Scarborough?), the social worker who was looking after him...careworker next? I think the statue in the attic was Kali who has pretty mixed interpretations ranging from a bringer of death to a maternal figure... Not sure how the old lady in the home fits in (former flame who escaped the ghost?), or the fact that he won't own up to how old he is - the pictures seemed to be from before his time - unless they're not of him...Or what the moving pictures are about!
Did think it was odd how he was clearly scared and desperate to leave the house but when the shell fell he said something almost reassuring, 'you'll be alright' or something? Maybe they're one and the same - she possesses him?
Looking forward to next week!
