I had owned this Dover selection for over 35 years before locating this used copy for my daughter. As E.F. Bleiler notes in his excellent intro, Dunsany is uneven, but of the 20-odd stories in this selection, I can say that over the period I've spent with it there is only one that hasn't at some point charmed me in some way (that one is The Coronation of Mr. Thomas Shap, which I still think is, at best, an unsuccessful experiment); and I raised my children on memorized retellings of How Ryan Got Out of Russia--making them think, for many years, that I had been shot out of a cannon in the Soviet Union--in the upshot of being sent by a secret society to sabotage a munitions factory, fortunately landing in England instead of on the moon, where the nasty Bolshies had tried to send me. (It is a great fantasy yarn, but the adult reader will notice above all that it pokes fun at the crude technologies Jules Verne had proposed a generation before.)
At its best--and much of its best is here--Dunsany's style is both rich in imagery and underpinned with a sardonic wit which he turns perfectly, for those who like sardonic wit (i.e., he runs strongly toward ironic or catastrophic endings with faux morals about the futility of ambition). What distinguishes Dunsany from the run of fantasy writers is that he tempers his obvious enjoyment in escapism ("strange worlds") with a sensibility that can best be termed satiric. We can never be quite sure whether Mr. Joseph Jorkens is a casual liar, a manufacturer of elaborate conspiracies--or possibly a truthful traveler within amazing venues.
Sorry it's out of print and no longer available from Dover @ $2.00.
