The murder at Ireland's eye

On a fine calm morning in September 1852, a strikingly handsome man and his beautiful wife stepped onto a hired boat in Howth Harbour, Dublin, to set out on a day trip. The destination was Ireland's Eye, a small uninhabited island less than a mile to the north of the harbour. He was an artist, she a keen and adventurous swimmer. By sunset, when the boat returned to fetch them, she would be dead.
