Murder in the Locked Room on the Isolated Island

The island owner's hired me as a detective at short notice to solve the locked-room mystery.

After searching the crime scene and the victim's home, I deduced the killer's identity. Then I followed the island owner back to the conference room and began presenting my deductions in front of everyone.

After a heated debate, I successfully identified the killer, but also exposed the fact that I was having an affair with the island owner's wife.

The killer finally confessed. She had wanted revenge on the island owner, but the victim discovered her crime, forcing her to kill. In the end, the island owner locked both the killer and me up.
