Cycling around the Australian holiday island of Rottnest, Becky and her friends make an awful discovery – a dead body beneath a cliff. Did the man fall, or was it murder? Becky can’t stop thinking about it. Then a chance discovery about the dead man’s name makes her wonder if this death could be linked to a murder that happened many years ago. Becky is determined to find out how. But as she gets closer to finding the answers, she finds she’s getting into great danger herself.
