question:
Passage: In September 1930 Heseltine moved with Barbara Peache into a basement flat at 12a Tite Street in Chelsea. With no fresh creative inspiration, he worked in the British Museum to transcribe the music of English composer Cipriani Potter, and made a solo version of "Bethlehem Down" with organ accompaniment. On the evening of 16 December Heseltine met with Van Dieren and his wife for a drink and invited them home afterwards. According to Van Dieren, the visitors left at about 12:15 a.m. Neighbours later reported sounds of movement and of a piano in the early morning. When Peache, who had been away, returned early on 17 December, she found the doors and windows bolted, and smelled coal gas. The police broke into the flat and found Heseltine unconscious; he was declared dead shortly afterwards, apparently as the result of coal gas poisoning.An inquest was held on 22 December; the jury could not determine whether the death was accidental or suicide and an open verdict was returned. Most commentators have considered suicide the more likely cause; Heseltine's close friend Lionel Jellinek and Peache both recalled that he had previously threatened to take his life by gas and the outline of a new will was found among the papers in the flat. Much later, Nigel Heseltine introduced a new theorythat his father had been murdered by Van Dieren, the sole beneficiary of Heseltine's 1920 will, which stood to be revoked by the new one. This theory is not considered tenable by most commentators. The suicide theory is supported (arguably), by the (supposed, accepted) fact that Heseltine/Warlock had put his young cat outside the room before he had turned on the lethal gas.Philip Heseltine was buried alongside his father at Godalming cemetery on 20 December 1930. In late February 1931, a memorial concert of his music was held at the Wigmore Hall; a second such concert took place in the following December.In 2011 the art critic Brian Sewell published his memoirs, in which he claimed that he was Heseltine's illegitimate son, born in July 1931 seven months after the composer's death. Sewell's mother, unnamed, was an intermittent girlfriend, a Roman Catholic who refused Heseltine's offer to pay for an abortion and subsequently blamed herself for his death. Sewell was unaware of his father's identity until 1986.

Passage: While Miss Marple and Mr Stringer are soliciting donations for a charity ("The Reformed Criminals Assistance League"), they visit Mr. Enderby, a rich and eccentric recluse. He tumbles down the long entrance staircase, apparently the victim of a fatal heart attack. Knowing that Enderby had a pathological fear of cats, Miss Marple becomes suspicious when she finds one in the house. She also finds a piece of mud bearing the print of a riding boot, but when she goes to Inspector Craddock, he is sceptical, believing that Enderby died of natural causes.
Undeterred, Miss Marple eavesdrops when Enderby's family gather for the reading of the Will. There are four beneficiaries: fourth cousin George Crossfield, niece Rosamund Shane, nephew Hector Enderby and sister Cora Lansquenet. Each receives an equal share of the estate. Cora declares that she believes Enderby was murdered. The next day, when Miss Marple goes to see her, she finds Cora dead, stabbed in the back with a hatpin. Cora's companion of many years, timid Miss Milchrest, can provide little information.
Miss Marple decides to take a "holiday" at the Gallop Hotel/riding school, as it is run by Hector Enderby and the other two surviving heirs and Miss Milchrest are staying there. When Inspector Craddock questions them and Rosamund Shane's spendthrift husband Michael, none of them can produce a satisfactory alibi for the time of Cora Lansquenet's death.
Question: What relation is Rosamund to Mr. Enderby?
answer:
niece.
