Sherlock Society Practice Test 2026 – Comprehensive Exam Prep

Choosing the most informative surveillance source hinges on finding footage that covers the scene and the crucial time window of the incident. Yadi’s suggestion to check Mr. Bailey’s surveillance is the best because footage from that location is most likely to capture the moment the event unfolded—who was present, where they went, and when actions occurred. This directly helps establish a timeline and identify people involved.

Footage from Grandpa might not cover the incident area or the exact time, and footage from Roberta or Alex could be from locations that don’t show what happened or may be incomplete. In short, the source closest to the event and time you’re investigating tends to provide the clearest, most relevant evidence.
