Compared to what you read:
 * How do the detectives approach the crime scene?

Tells Him not to touch anything in the crime scene so they can see what actually happened and hopefully find clues Then they look for evidence: muddy because it was raining the night of the crime
 * testimonial evidence** - Ask questions about what happened that night but they seem to believe what they are told with out much questioning
 * physical evidence** - take pictures of the blood stains that are on the floor, they check for foot prints on the door mat
 * conditional evidence** - they see that swan must have entered through the door because if he had come through the window his shoes would have been
 * associative evidence** - asked if they had any prior connections with swan
 * What techniques for solving the crime are available (Ex - DNA? Fingerprint? etc.)

They could have used finger prints but for evidence that swan had been over to there house before but he was smart enough to wipe them off with a rag, but they did think at first that swan was the one that stole all of the notes that he actually did because he made swan pick them up off the floor. They did find fibers on the bottom of swans shoes that came from the mat outside the door which confirmed that he didn't really come in through the door like he said. Also they saw that the stocking that he supposedly tried to kill her with had been mended with the same silk that was in her sowing box, proving that she he didn't really bring a stocking to try to kill her
 * How is the crime solved?

the crime is finally solved when the investigator figures out about that bank statement and all the money he had, and when he switches the coats and figures out that swan did remember to put the key back and the key he took out of swans pocket was actually swans and not his, and the real key was under the carpet on the step the whole time.
