Good sound quality, easy-to-follow and *Very* suspenseful without the narrative being confusing (as with some previous episodes. The detective was really "on the ball" in this case—he didn't miss a thing!  I couldn't help thinking, if only this had been written as a "whodunnit" where the listener didn't know the culprit/motive from the beginning and had to figure it out along with the characters, it would've been that much more satisfying; but it was still an extremely captivating story. :)  Kept my attention until the very end!
