Here is a fantastic opportunity for you to grab sone criminally good books (see what I did there?) that will cost you none of your hard-earned cash.
For the record, this is a curated page of crime and detective novels which are only available this month. So download as many as you fancy as soon as you can.
And, yes, it is true that the Jake Adkins novella, Proof is on the list, but I encourage you to try as many as you can from all the authors.
Fill your boots.
