Why it matters
Ritual imagery and an archaeological treasure hunt sit over a case whose strongest manipulation is thoroughly modern.
Farmer Alex Preston is found dead at the centre of Crowcall stone circle shortly before the spring equinox. He had planned to plough the meadow, bringing him into open conflict with the New Dawn Druids who regard the site as sacred.
When a member of the Druid group is also killed, Barnaby looks beyond the apparent religious feud. Maps pointing towards Anglo-Saxon treasure, a valuable painting and tensions within the police investigation redirect the case towards people who know how to turn belief into leverage.
Break the seal: reveal the finding
Who was the killer in The Sleeper Under the Hill? (spoiler)
The Druid conflict is exploited as camouflage. The maps, treasure and painting reveal a manipulator who has arranged both the crimes and the suspicions surrounding them.

Break a second seal: reveal the verified killer
Who was the killer in The Sleeper Under the Hill? (spoiler)
Caradoc Singer · Sgt. Trevor GibsonSinger manipulated Gibson into killing Alex Preston and Leticia Clifford and staging both deaths to implicate the Druids while they concealed the Saxon treasure. Singer then killed Gibson when he tried to flee; Singer's instigation and Gibson's physical killings remain distinct.
Verified motive
Singer's compulsion to possess the Gorse Meadow Saxon treasure drove the scheme: Alex wanted to report the find lawfully and Leticia's investigation threatened its concealment. Singer used Gibson to remove them and frame the Druids, then killed Gibson when his accomplice tried to flee and could expose the collection and murders.
Verified important clue
Archive case 86 · checked 16 September 2026The hidden room containing Singer's art collectionThe different room visible in Singer's own recorded tour reveals a concealed gallery of valuable works and exposes his supposed poverty as a cover; the collection supplies the ownership obsession behind his pursuit of the Saxon treasure and his manipulation of Gibson, while the staged Awen brooch keeps their roles distinct.
