Gunpowder Treason and Plot

In November of 1978, Constable Olivia Daniels and her trainer Constable Stan Polanski are dispatched to investigate a suspicious shooting in a Nova Scotia barn. Within minutes of arrival, they are ordered to turn the investigation over to RCMP Security Service, but not before Olivia stealthily photographs the crime scene with her own camera. There certainly seems to be something 'untoward underfoot'.
Their careers are immediately altered as are their personal lives. In the ensuing decades, innocent voices are silenced, incriminating evidence concealed, internal corruption suspected. Then, a chance meeting in an airport lounge triggers a cascade of revelations and events that threaten to bring down highly-connected spies, with potential global repercussions.
