Thomas Sefton was an English cook who worked on the Obra Dinn during her last voyage in 1802. He was struck dead by a mermaid's tail in Unholy Captives, part 2.


Cook Thomas Sefton demonstrates the 19th century kitchen hygiene standards in Murder, part 2.

Sefton was the ship's cook and was responsible for providing meals for the crewmen. He was first seen witnessing the execution of Hok-Seng Lau on the main deck alongside butcher Emil O'Farrell[1]. Neither of them appear in the Justice at Sea sketch, probably because they are outside the field of view of artist Edward Spratt.

While a group of sailors were carrying some mermaids to the lazarette, Sefton came up to observe and joke about frying them up for the crew's meal. In his folly, Sefton reached for a shell on one mermaid as a sailor warned him to stand back. The mermaid struck him with its tail, killing him.[2]

The following commotion caused the sailors carrying the mermaid to lose their balance, resulting in William Wasim to break his neck falling down the stairs to the gun deck.[3]

After an insurance assessment on the Obra Dinn incident, the East India Company awarded Sefton's estate £40 in outstanding wages.[4]


Sefton can be identified in Unholy Captives, part 2 from his apron, the two-pronged fork he carries, and his jokes about turning the mermaids into a meal.


Sefton appears in only two memories. Chronologically, he first appears in Murder, part 2. He appears in the Under Way sketch next to butcher O'Farrell.
