After forty five years as a professional stalker, and 43 years as the head stalker on the Invercauld Estate, Peter Fraser is working his last red deer stag season before his retirement in November. (Stalking is the term used in Scotland for hunting and shooting deer.) The stalking season runs from July until October.

According to the Invercauld Estate website, "the land has been in the ownership of the Farquharson family for many centuries and extends to approximately 200 square miles of spectacular scenery. The Estate is managed commercially but with great respect for the natural environment."
