Disclosure: I obtained the free Kindle version of "Locked Room - A Katla Killfile" today. The comments that follow are my own personal opinion. I received NO compensated of any kind, or from any one, to provide this review.
Totally enjoyed this short story. Definitely an efficient kill and enough detail to give the reader a visual of the event. Bought the first novel in the Amsterdam Assassin Series and decided to read the three "prequels" first. Very glad I did. Proceeding to the next short story and will review it as well.
