X Minus One premiered in April 1955 on NBC and ran until January 1958. Like its predecessor series, Dimension X, X Minus One featured stories by the greatest names in modern science fiction: Ray Bradbury, Robert Heinlein, Clifford Simak, Robert Bloch, and many more.
One Protective Mimicry finds us with Bamhoser, a special agent in "United Galactic Federation Department of Treasury, Investigation Division, Currency Section". Bamhoser has to track down a counterfeiter who is believed to have created a matter duplicator. His investigation takes him deep into the jungles of a humid, alien world where primitive natives live without sophisticated machinery.
The counterfeiter captures Bamhoser and, in his arrogance, the thief explains his methods. When Bamhoser’s companions arrive and a battle breaks out, an unexpected event wins the day for the good guys. (Made me think of a contemporary sci fi with a similar theme.)
The story is quick and I had to laugh at the ironic ending. There is some fun, 50’s appropriate views of women and repartee among the characters. The descriptions are well done, putting the reader in the stifling jungle, including a character blood-sucking bug.
