A Case of Identity – Randall Garrett - A murder mystery in the sword and sorcery land of an alternate history. – 2.5 stars

The Mary Celeste Move – Frank Herbert – What might be the consequences in a crowded, fast paced world, if people suddenly decided to try to get away from it all? - 1.5 Stars

Of the group I think the stories by Spinrad and McLaughlin have done a reasonable job of standing the test of time. Sunjammer is ok but the plot has had a much better presentation in other science fiction short stories. A Case of Identity is one of Garrett’s Lord Darcy stories so if you are a fan of that character you might want to consider reading it. The book is a quick read and, for me, the first 2 stories made the reading effort worthwhile. ( )
