Pursuit is a science fiction novella by American author Lester del Ray, first published in 1952.

A man wakes with no memory of the last seven months. He only knows he's in danger. No sooner does he leave his apartment than it explodes in flames. He sets off running through New York.

A nicely done paranoid sci-fi story of heat rays, disintegrating men, exploding cats, and trips to the moon. Aliens must be involved--what other explanation can there be?
