I found this to be one of the most riveting Kojak episodes of the first two seasons - just great stuff.
Of course, sniper killings usually make for interesting stories. This one has a twist to it, involving a second person The first person was fascinating to me because seeing Bruno Kirby Jr. at such age was almost a shock. He really looks young here, about 17-18 although he was around 25, and does an excellent job as "Keith Wicks," a man out for revenge for his father's killing two years earlier.
Eugene Roche plays the other man guest character: bookkeeper "Seymour Haywood." Now here is a man with serious mental problems. Roche, a fine actor whose name you might not know but whose face you would remember, really had to put the emotion in this guy. "Haywood" a little far out, but life is filled with many sad, complicated people who do strange things.
Anyway, those two characters are really memorable and drive Kojak and his boss crazy during this crime spree.
