In 1920, tired of the lecture circuit, Sir Ernest Shackleton began to consider the possibility of a last expedition. He thought seriously of going to the Beaufort Sea area of the Arctic, a largely unexplored region, and raised some interest in this idea from the Canadian government. With funds supplied by former school friend John Quiller Rowett, he acquired a 125-ton Norwegian sealer, named&nbsp;<i>Foca I</i>, which he renamed&nbsp;<i>Quest</i>. Despite his harrowing experience recounted in&nbsp;<i>South</i>, the lure of Antarctica was too strong for Shackleton to resist, so he started his fourth and final trip in the ill-suited&nbsp;<i>Quest</i>&nbsp;in 1921. But when Shackleton died suddenly in South Georgia, Frank Wild took charge of what remained, resulting in this eyewitness account of the famous Arctic explorer&rsquo;s final expedition.
