Final answer:
A left-handed person is suspected of committing the murder, with additional context suggesting a novice British culprit. The situation involves analyzing provided evidence such as the use of American dollars and London newspapers.
Step-by-step explanation:
The experts hired by Sam's brother concluded that a left-handed person must have committed the murder. This determination might be derived from evidence available at the crime scene, which could include things such as the angle of the inflicted wounds or the position of objects that were interacted with by the perpetrator. When analyzing the passage provided, it's clear that the crime was committed by someone with limited experience, possibly a native of Britain, as suggested by the irrelevant distraction involving American dollars. The presence of London newspapers might offer further clues as Sam's brother continues the investigation.
However, if the question was about the legal repercussions for a woman who murdered her husband, the answer would depend heavily on the location and timeframe, as laws regarding capital punishment vary greatly. In some jurisdictions and historical periods, she might indeed face execution, while in others, she could face life imprisonment or another form of penalty. Modern legal systems typically consider numerous factors before deciding on the sentence, including the circumstances of the crime and the defendant's history.
