In The Sherlock Society, which department is the Secret Service part of?

• A. Homeland Security
• B. Treasury
• C. Justice
• D. Defense

Answer: (A)

Understanding how protective agencies are positioned within the government is key here. In the current government structure, the Secret Service sits under the Department of Homeland Security. This placement, established in 2003 with the creation of DHS, aligns its protective mission—safeguarding national leaders and major events—with broader homeland-security efforts and coordination with other security agencies. Historically, the Secret Service was part of the Treasury, which is why you might see references to it there in older contexts. The other departments don’t align with its modern role: Defense is the military, and Justice oversees agencies like the FBI, while Treasury was its former home, not its current one.
