A senior Regina lawyer, Garrett Wilson, QC, was a key Liberal during the administration of Premier Ross Thatcher, Colin's father. His background made him familiar with the principal players in the Thatcher case long before it came to national attention. His long association with the Regina police as counsel gives him insight to the long and difficult - and continuing - investigation. Garrett has continued to follow the Thatcher case during the more than fifteen years since the original trial ended.

Garrett has also written Diefenbaker for the Defence (Lorimer, 1988), an account of the legal career of the former prime minister, and Guilty Addictions (NeWest, 1999), a fictional account of corruption in the government of Saskatchewan that was short-listed for two awards.
