How would Booth and Herold know who Cox sent was there to help them?

• A. The person would use a three-note whistle when he arrived
• B. The person would wear a red scarf
• C. The person would shout 'help'
• D. The person would arrive with a map

Answer: (D)

The situation hinges on using a concrete, verifiable signal to confirm the helper’s identity and provide direction. A map is a practical, specific item that Cox could arrange for the incoming helper to bring. Booth and Herold could check the map against their agreed plan and use it to navigate the escape, knowing they’re being helped by the right person. Other signals would be unreliable or risky: a whistle could be faked by someone else, a red scarf could be borrowed or borrowed by others, and shouting “help” would draw attention and wouldn’t confirm who had arrived. The map both verifies identity and serves as a navigational aid, making it the clear method they would rely on.
