The fierce storm shook the old manor precisely at midnight. Inside, guests gathered for the annual reading of the will. Sir Reginald’s lawyer stood before them with a solemn expression. The intended beneficiary was found dead in the library instead. A gunshot wound to the chest revealed the brutal truth. Every guest had a motive; now each was a suspect. The storm’s rage mirrored the chaos within those ancient walls.
