Eric Edgar Cooke terrorised the people of Perth for years, but they didn’t know it. The people didn’t know that the nighttime prowler breaking into people’s homes and stealing money from purses while they slept, the peeping Tom who watched women getting changed and young couples getting busy, the maniac striking women down in deliberate hit-and-runs, the murderer of two young, well-known socialites, and the perpetrator of the Australia Day weekend massacre were all one person. How could they? What kind of a criminal commits such different crimes, with different MOs and no set victim type? Eric Edgar Cooke was a criminal unlike Perth had ever seen before.
