First published in 1949 this is an early anthology of short SF stories. All are from the 1940s, easily a decade before the "Golden Age of SF" in the 1950s-1960s. Some of the stories are just fantasy and some are more mystery. Several were written by new authors who went on to make a name for them selves. These include Ray Bradbury, A. E. van Vogt, Frank Belknap Long, and William F. Jenkins (as Murry Leinster). Some of the stories are in the fading style of earlier decades and some show promise of the SF to come. ( )
