James Schuyler Grim, or "Jimgrim". As created by Mundy, Jimgrim was an American who had been recruited by the British intelligence services because of his in-depth knowledge of Arab life. Mundy claimed that Jimgrim was based on a real individual, whose identity he refused to reveal, while later biographer Brian Taves has suggested that the character was heavily influenced by T. E. Lawrence. The first of these Jimgrim stories, "The Adventure of El-Kerak", appeared in Adventure in November 1921; the second, "Under the Dome of the Rock", appeared in December, while the third, "The 'Iblis' at Ludd", appeared in January 1922. In August 1922, Mundy published "A Secret Society", in which he took Jimgrim out of Palestine and sent him to Egypt. This series of novelettes promoted the cause of Arab independence from British imperialism and presented an idealised image of the prominent Arab leader Faisal I of Iraq. These early Jimgrim stories were an immediate success for Adventure, however Bobbs-Merrill were nevertheless not keen on them and urged Mundy to write something else. The company had repeatedly lent money to Mundy, who was now heavily in debt to them. In October 1921, Mundy left New York and settled in Reno, Nevada, where Ames joined him. He initiated divorce proceedings against Rosemary in a Reno court. The case was eventually heard in August 1923, with Mundy alleging that he wanted a divorce because Rosemary had deserted him. She denied the allegations, and the judge dismissed Talbot's case, adding that from the evidence Rosemary herself would be entitled to sue for divorce, which she nevertheless refused to do. Mundy meanwhile continued writing prolifically, producing 19 novel-length stories from 1921 through to the end of 1923, something that he found particularly tiring. In November 1922, Adventure published Mundy's The Grey Mahatma, which would later be republished under the title of Caves of Terror. Taves described Caves of Terror as "a landmark in Mundy's career", being "one of [his] most unusual and extraordinary novels". The work included characters such as King and Yasmini who had been a part of Mundy's early oeuvre, as well as more recently developed characters like Jeff Ramsden from his Jimgrim series. It revealed Mundy's growing interest in Asian religion and also introduced a number of fantasy elements not present in his earlier work. The readers of Adventure voted it as their favourite novel of the year. At this
