Etymology
A sleuth was originally a “track or trail,” preserved in sleuth-hound, a bloodhound. The detective sense likely comes from shortening that name after its figurative use for a keen, relentless investigator.
In context
when the sleuth showed him the proof, the matching fingerprints, the timeline, the motive, the officer's expression shifted from doubt to shock. Together, they revisited the evidence
