Cannon R6 - Gadget Planet

A cannon (plural either cannons or cannon) is a large- caliber gun classified as a type of artillery, which usually launches a projectile using explosive chemical propellant. Cannon and canon are occasionally confused by writers, but the two words have independent origins, and do not share a meaning. Cannon is most frequently found used in the sense of "a large gun," and can be traced to the Old Italian word cannone, which means "large tube." Cannon, big gun, howitzer, or mortar, as distinguished from a musket, rifle, or other small arm.

Modern cannon are complex mechanisms cast from high-grade steel and machined to exacting tolerances. Frank Cannon, a husky ex-cop and culinary enthusiast, solves tough cases as a private investigator. Cannon is hired by a San Diego industrialist to protect his daughter from a psychotic man, and then he gets framed for killing the man.
