Set after the events of "Procrustes" (see the collection Crashlander), Shaeffer finds himself onboard a passenger ship, the Odysseus, just as it is being captured by a ship of Kzinti pirates. Shaeffer is taken prisoner and develops an unusual alliance with a non-practising Kzinti Telepath, "Fly-by-Night" and his octopus-like Jotoki slave, "Paradoxical".
