The Bomb Circle is the monument to Frank’s second murder – that of his younger brother. After a heavy storm, a bomb was uncovered, and Frank persuaded his brother that it was a bell. He told him that the harder he hit it, the louder it would ring. Obviously, hitting the bomb would cause it to explode. It shattered the rocks around it and created a circle of pointed stones. These were partially covered when the sand returned, and a circle remained to remind Frank of his deed.
