Oh Mesmerist From Mimas!

A spacefaring trader arrives at a Martian cargo mart with a captive Mimasan smiley, a small insubstantial creature whose mating call radiates a narcotic aura of peace that melts rivalries and confounds commerce. He attempts to profit by offering the creature to buyers while concealing a second captive, but the smiley's influence complicates bargaining, alters behavior even among hard-bitten officials, and draws violent interest from professional thieves and corporate agents. The narrative follows his efforts to sell the creature amid theft, pursuit, and legal entanglements, examining tensions between profit, empathy, and the unpredictable social effects of an alien presence.
