trading voyages, Worsley wrote books and articles. Two of these, Shackleton's Boat Journey and Crossing South Georgia were published as serials in the periodical Blue Peter in 1924, and were well received. These books were published together as a single volume in 1931. His book was considered superior to Shackleton's own account, published as South in 1919. In 1938, a fourth book, First Voyage in a Square-rigged Ship was published. When his financial circumstances required it, which was often, Worsley would write an article for money. His topics would range from the dogs used on the expedition to the pipe smoking habits of his Elephant Island cohabitants. Worsley also conducted lecturing tours for income, his profile enhanced by his publication record. As sailing commissions at this late stage of his life were in short supply, his lectures became more important as a source of income. He mainly lectured on his voyages with Shackleton, whose wife lent Worsley several of her late husband's slides to enhance his talks. In later years, he added talks on his own voyages to his repertoire. His lectures were well received with glowing reviews in local newspapers. His profile was boosted following his appearance in the film South, released in 1933, for which he provided an accent-free narration. The film was based on Frank Hurley's cine film of the Endurance expedition, intercut with photographic slides. He made an onscreen appearance in the film, showing the audience several artefacts from the expedition. Like his books, the film was very well received. In the 1930s, Worsley was part of a yacht and ship delivery company, Imray Laurie Norie & Wilson Limited. His personal experience was a key selling point in the company's commercial literature. In 1937, the company completed over 50 delivery voyages. The longest delivery was that of a steamer destined for Hong Kong, which took three months. On many of these voyages he was accompanied by Jean, who also enjoyed sailing. Treasure hunting Even into his 60s, Worsley still sought adventure. In 1934, he was asked to join the Treasury Recovery Limited Expedition which was organised to locate treasure allegedly hidden at Cocos Island by pirates. In earlier times, the island had been used as a base by the pirates to attack Spanish ships transporting gold from South America back to Spain. At the time of mounting the expedition, it was believed that between £5 million
