He Never Came Back — Helen McCloy

An attractive but short-sighted New York girl picks up a pendant from a twenty-cent jewelery stall and is surprised to find herself the centre of some strange events. A man is run over- not quite by accident, her boyfriend disappears, a Burmese shows her a crouching cat, and the pendant turns out to be more than glass.

Gradually she comes to realise that she is in extreme danger.
