Murder Secret 4K 09/26 Blu-ray (Rental)

Invited by an Aunt Marta he hasn't seen in thirty years, Richard Hamilton travels to his estranged relative's countryside home with his wife and two children in tow. On arrival the family finds not Marta but the property's caretaker, Thomas, who tells them she has been held up and will join them the following morning. When she again fails to appear the next day, a sense of creeping unease mounts — and as an unseen assailant sets about dispatching the family members in various gruesome ways, Aunt Marta's dreadful secret gradually begins to reveal itself.
