Kreativity for Kats & Other Stories

Here are three stories by the inimitable Fritz Leiber, all from Galaxy Magazine: Kreativity for Kats 1961 - aliens do live among us; The Last Letter from Galaxy 1958 - a hand written letter paralizes the postal service; and The Big Engine, 1962 - what makes everything go? perhaps this man is right. All are different and all are very enjoyable. - Summary by Phil chenevert
