The novel, written in the first person, adopts the voice and eyes of Tom Cutter, an aircraft pilot, engineer, and
entrepreneur. The novel starts with Cutter's boyhood—he gets a job with the Alan Cobham "National Aviation Day" flying
circus, of barnstorming aircraft which take customers up for short joyrides, with other entertainment provided. Cutter
meets Connie Shaklin, a boy a little older than himself, half Chinese and half Russian but a British subject, and who
even then has a deep interest in religion, taking days off to visit houses of worship. When the air circus folds, the
two drift apart. Cutter apprentices in aviation engineering, and also learns to fly. He marries a co-worker named Beryl,
and soon afterwards is posted overseas as a civilian to do -related aviation work during World War II. While
overseas, he learns his wife has been unfaithful. He is stern, but forgiving, in letters to her, but when she learns
that he is soon to return, she commits suicide. Cutter blames himself. He cannot stand to return to his old job or
remain in England, so he buys and rebuilds a small aircraft and flies it to Bahrain, then a British protectorate, to
start a freight business. His service fills a need in the Persian Gulf, and he gradually expands, acquiring more
aircraft but never incorporating his business. He keeps his business costs down by hiring no European staff, only what
he calls Asiatics. Hired to take a load to Indonesia, he is surprised to find Shaklin there, working for a runner who
has been arrested by the Dutch, then in control of much of the country. Shaklin has maintained his interest in
spirituality, but is also a very experienced engineer. Cutter is able to hire him and to purchase the runner's plane.
Both prove major assets to his business. As Cutter retrieves the plane from a small village in Cambodia, he notes that
Shaklin has become a religious leader of sorts there. Shaklin proves a major influence both on Cutter's staff,
impressing on them the need for good and honest work, and on the local Arab community in Bahrain. Putting his teachings
in terms of Islam and the Koran, he soon gains influence over the local sheikh, who offers Cutter a substantial
interest-free loan for a large aircraft he needs. He accepts, and when he returns from Britain with the aircraft, finds
that the authorities are very much upset about the transaction, decrying Shaklin's influence over the sheikh. Cutter
does his best to soothe matters, but the British order Shaklin out of the area. In the interim, Connie's sister,
Nadezna, has arrived from California to become Cutter's secretary. She and Cutter rapidly find themselves attracted to
each other. Since one of Cutter's customers needs repeated trips to Australia, and since his Asian staff are not welcome
in White Australia, Cutter sets up a forward base in the idyllic island of Bali, and assigns Shaklin to head the
operations there, more as a sinecure than anything. One of the local girls is soon in unrequited love with him, while
Shaklin busies himself learning about the local religion. Back in the Persian Gulf, Shaklin's expulsion has indirectly
occasioned a more reasonable attitude on the part of the British. The Arabs now hold Shaklin in almost divine regard.
The Sheikh's has started failing, and he expresses a desire to see Shaklin before he dies. He and his entourage
travel to Bali to visit Shaklin. This pilgrimage both inspires others to similar travel — and stirs up the Dutch
colonial administrators, who expel Shaklin from Indonesia. The Sheikh's doctor has expressed concerns about Shaklin's
, and he is soon diagnosed with leukemia — at that time a death sentence.
