The Evil Craftsman of the Haunted Tomb

For generations, my family has made tombstones. After my grandfather passed away, I inherited the craft. Since death touches every household, I made a decent living, until one day a man dressed all in black came to ask me to carve a palm-sized stone plaque. Then I learned from my childhood friend that the man had actually been dead for years. That was when a story from fifty-six years ago began to unfold. My grandfather had been involved back then, and as his descendant, I was inevitably drawn into the old feud.
