Tom Sherbourne was a soldier in Europe during World War I. Deeply affected by his experiences, and the guilt he feels for the lives he took, he signs up for a job as a lighthouse keeper, taking postings at the most remote and lonely lighthouses around Australia. When a posting becomes available on Janus Rock, a place so remote and lonely, other lighthouse keepers have been driven mad, Tom agrees to go, first as a temporary replacement, and later as the official lighthouse keeper. The only human contact is the supply boat that comes every three months.
Tom falls in love with a young woman, Isabel, and despite his initial reservations, marries her and brings her to Janus Rock. To begin with, they are blissfully happy, alone with each other in a place nearly a day’s journey from the coast. After several years, things are more strained. Isabel has miscarried twice, and two weeks after her third pregnancy ended in stillbirth, she first believes herself to be hallucinating, when she hears a baby’s cries on the island. A small boat, with a dead man and a living baby, has washed up on shore. Tom, always meticulous in his record keeping, wants to report the findings to the authorities right away. Isabel begs him to wait, just a day, so she can spend some time with the baby. Against all his better judgement, Tom agrees, and he’s then persuaded by his desperate grieving wife that they should just bury the dead man, and claim the baby as their own, naming her Lucy. No one knows that Isabel miscarried, they can just pass off the foundling child as their own. More on my blog.
