The supreme spy or greatest espionage agent; a master intelligence operative who leads all other spies or is the most skilled at gathering secrets.
From 'arch-' (chief, supreme) plus 'spy' (from Middle Dutch 'spye,' to look or watch). The compound suggests the most accomplished or highest-ranking secret agent.
While James Bond is a famous spy, if he were an 'archspy,' he'd be the one running all the other secret agents, like M in the films but actually doing the spy work!
