I went into this anthology totally blind. I have not read any of the authors or even heard much about them. 

I can honestly say I very much enjoyed my reading experience. It is a great collection of mystery and suspense. Each of the stories feels different, and yet you totally get the running theme.

The trick with short stories is to give enough to get the reader to understand the plot and leave with the confidence they got a good conclusion,  and doing all that on just a few pages. 
All the authors, in my opinion, succeeded.
