Shi Pei Pu, a Beijing opera singer and spy whose sexually convoluted love affair with a French Embassy worker created one of the strangest cases in international espionage and was the inspiration for the Broadway show "M. Butterfly," died in Paris on Tuesday.

Shi (pronounced Shuh), who was convicted of espionage in France in 1986 along with his lover Bernard Boursicot, was believed to be 70. He also had been believed for years to be a woman, at least by Boursicot, who served time in prison after the affair and became a laughingstock in France.

Boursicot, 64, who has been living in a nursing home in France while recovering from a stroke, showed no sadness when he learned of Shi's death in a telephone interview.

"I'm not surprised," he said. "It is a long time he has been sick. Now it's over 40 years."

Asked if he had any sadness at all, Boursicot said: "He did so many things against me that he had no pity for, I think it is stupid to play another game now and say I am sad. The plate is clean now. I am free."

In the 1988 Broadway play and the 1993 film "M. Butterfly," Boursicot was depicted as a high-ranking diplomat and Shi Pei Pu as a beautiful female opera singer who met in 1964. In fact, Boursicot was a 20-year-old high-school dropout who had finagled a job as an accountant at the newly opened French Embassy in Beijing. His few sexual experiences had been with male schoolmates, and he was determined to fall in love with a woman, he wrote in his diary.

Shi Pei Pu was 26 when they met, delicate and charming. He lived as a man and taught Chinese to the diplomatic wives. He told Boursicot he had been a singer and a librettist in the Beijing Opera. One night in the Forbidden City, Shi told Boursicot a story no romantic could resist: Shi said he was a woman who had been forced to go through life as a man because her father required a son. A short time later, the men became lovers, although the sex, Boursicot would later say, was fast and furtive, always carried out in the dark.

When the affair was discovered by Chinese authorities, Boursicot - through Shi - passed them French documents, first from the embassy in Beijing and later from the consulate in Ulan Bator, Mongolia.

Boursicot spent most of his life outside China and was romantically involved with men and women. On one of his rare visits to Shi Pei Pu, Shi presented Boursicot with a 4-year-old boy, Shi Du Du, who Shi said was their son.

In 1982, Boursicot - then living openly with a male companion, Thierry Toulet - arranged for Shi Pei Pu and Shi Du Du to live with him in Paris. Shortly thereafter, Boursicot and Shi Pei Pu were arrested. Shi first told the police he was a woman, but he admitted the truth to prison doctors.

Shi Du Du explained the mystery of where he came from in his statement to the police: He was from China's Uighur minority, he said, and had been sold by his mother. "It was not that my mother did not love me," he said. "We were starving."

Boursicot, hearing that Shi Pei Pu was a man and always had been, sliced his throat with a razor blade in prison.

In 1986, Shi and Boursicot received six-year sentences for espionage. They were pardoned a year later. Shi is survived by Shi Du Du, who lives in Paris and who, Boursicot said, has three sons.

Although Boursicot and Shi occasionally spoke over the years, relations were strained. Boursicot said they last spoke a few months ago and Shi told him he still loved him.

Shi enjoyed the spotlight, performing in public as an opera singer, but disliked talking about his romance with Boursicot.

"I used to fascinate both men and women," he said in a rare interview in 1988. "What I was and what they were didn't matter."
