Sandwiched between the mainland of Singapore and the Malay Peninsula, in the Straits of Johor, lies the small island of Pulau Sarimbun. The island lies within the Singapore Air Force live firing area and is restricted to casual visitors, but back in the early 1900s, it was a popular picnic spot and for nearly a decade, it was the retirement home to an Englishman named William Arthur Bates Goodall.
