The term 'MANY A BUGGER' can be solved by the three letter word 'SPY'. A SPY is a person who secretly collects information about an individual or organization for a government or other organization. Spies often use covert methods to obtain information, such as surveillance, eavesdropping, and bribery. They may also use more sophisticated methods, such as hacking into computer systems or using sophisticated surveillance equipment. Spies are often employed by intelligence agencies, military organizations, and law enforcement agencies.
