1. Oscar Brodski's body on the railway

   The burglar Silas Hickler kills the diamond merchant Oscar Brodski in his cottage, then lays the body across a railway line so the train will make it look like an accident or suicide. Thorndyke sees that there is very little blood at the scene, which means the injuries were inflicted after death. He then follows microscopic traces, including fragments of Brodski's spectacles and fibres on his clothing, back to Hickler's house, showing that the staging itself produced the evidence.

2. The inverted detective story structure

   The reader first watches the whole crime from the criminal's side, including motive, method and cover-up. Only then does the detective investigate. Since the question of who did it is already answered, the suspense moves to how the truth will be recovered, and the reader can check each deduction against facts they already know.

3. Concealment generates its own incriminating traces

   Each thing a criminal does to hide a crime, such as moving a body, faking a scene or laying a false trail, is another physical act, and every physical act leaves residues and inconsistencies. Elaborate premeditation therefore tends to multiply the evidence against the criminal. A cover-up has to be consistent with physics and physiology in every detail, while the investigator needs only one mismatch.

4. Physical evidence as a witness that needs interpretation

   The dead and their surroundings 'sing' through blood, dust, fibres and wounds, and unlike human witnesses they do not forget or lie out of self-interest. But matter only testifies correctly when an expert reads it correctly. Traces such as fingerprints can be forged, so an investigator must test each clue against every other clue rather than treat any single one as conclusive.
