Wasp, by Eric Frank Russell.
You know how distracting it can be when a wasp flies into a car that’s speeding down the highway? One little wasp could cause a deadly car crash and, best of all (for the wasp), it doesn’t even have to sting the driver. All it has to do is… distract.
James Mowry has been sent to Jaimec, one of the planets of the Sirian Empire, to be a wasp. His mission: to single-handedly disrupt Jaimec society, government, and military establishment.
James Mowry is very good at his job.
Don’t let the thinness of the book deceive you. This is a very good book. Recommended.
