It is slow going with an unidentified victim. None of the locals recognize the body.
No motive is possible without knowing who has been killed.
I reluctantly admit I am far from an observant blogger. I did not see coming in the book how the pivotal evidence would be found that led to the victim's identity. There was actually a visual image in front of me all the time. The image is part of this post . Sigh!
When the body is identified Bony can start gathering direct information from the locals during their daily drinking at the hotel bar. Bony shouts his share of beer. They are living in a time when little attention was paid to drinking and driving.
While glad to read another Bony story I found The Clue of the New Shoe a rather average story. It was more an ordinary undercover detective mystery.
Bony is always more observant than the average detective and does use his tracking skills in the book but the location and other characters did not show Bony at his best.
