"Ray Carver, vacationing top-notch Earth detective, looks for the first interplanetary killer and finds a wife."

Carver and his manservant Murphy make nabbing a vanishing murderer look easy, but The Green Hornet and Kato they ain't.

Comment: This could have been a real whingdinger, but there's no real mystery here—and even the artist gets it wrong. Disappointing.

Typo: "Its not a receiving set"
