The grand mansion loomed darkly in the fog as Inspector Lane approached the bloody crime scene of the murdered aristocrat. Inside the library the body of Lord Blackwood lay sprawled across the floor with a dagger protruding from his chest. The butler claimed he heard a loud scream around midnight but found nothing unusual when he checked the rooms later. Footprints in the garden suggested an unknown intruder had entered through the window after climbing the ivy covered wall outside. The assembled family members all had strong motives for the murder making this investigation particularly challenging for everyone involved now.
