Cannon (played by William Conrad) was certainly a different kind of private investigator. He was crabby, overweight and worked alone. Certainly not as sophisticated as other television private eyes. Despite this the series was quite successful during its 5 year run. Season two was probably when the series was at its most popular and even got an Emmy nomination for Best Drama Series.
