'London Falling': A teenage imposter, an aging gangster and a body in the Thames

This NPR book review by Frank Langfitt on Patrick Radden Keefe's investigation carries strong credibility — NPR maintains rigorous editorial standards, and Langfitt is an established foreign correspondent with expertise in international reporting. The article focuses on a dramatic true-crime narrative (a teen's death and double life) presented through Keefe's investigative lens, which should provide substantive detail and sourcing; however, the metadata provides limited information about the book's actual findings, sources cited, or Keefe's investigative methodology, so assessment of reporting depth relies on NPR's general standards rather than visible specifics here. Readers should note this is a review of another journalist's book rather than original reporting, so credibility ultimately depends on Keefe's underlying investigation, which isn't detailed in this metadata.
