This is an old favorite about a shape changing species that lives with man. It's completely SF, although it has paranormal elements, but they're explained through science. Van Vogt creates a mental logical structure that's interesting & packs several adventures into this book. I think there are 3 stories that were published separately. ( )

With possibly one of the worst beginnings of any book I have ever finished, The Silkie turned out to be a not bad read. Essentially three stories of progressing silliness based around the actions on one particular Silkie, in his attempts to `save' Earth.

You get the feeling that Vogt was possibly aiming for a 4 Laws equivalent with the logic of levels; this fails miserably but doesn't impede the book. Though I wouldn't try to think about it too much. ( )

The adventures of Lensman type supercop the Silkie. Several stories -each more insane than the last. Classic Van Vogt lunacy. Nothing perfect-but a mind blower. ( )

My favorite van Vogt. ( )
