After the tragic death of his younger brother, eleven-year-old Artur feels responsible for the accident, and a year later is still dejected with guilt. His parents, wanting time alone to try to save their marriage, send their remaining son away for the entire summer--to live in a cabin on a lakeshore with his crazy aunt. Artur, feeling this is just punishment, first just mopes around the cabin, feeling he should be in prison for what he has done. Soon, however, he meets Sam, a girl his age who lives in the cabin next door. While spelunking in a secret cave only Sam knows about, they find a clue written by a boy who drowned in the lake two years earlier. It seems on the same day he drowned, the boy found stolen bank money from a robbery. Two of the three bank robbers were caught, but the money was never found. Will Artur and Sam find the stolen bank money before the third bank robber? The adventure leads to a stunning climax where Artur must not only save his friend, but finally deal with the death of his younger brother. This may be a story for ages nine through twelve, but anyone of any age will enjoy it.
