池边的幻影 (1946)

The Hollow is a work of detective fiction by British writer Agatha Christie, first published in the United States by Dodd, Mead & Co. in 1946 and in the United Kingdom by the Collins Crime Club in November of the same year. The American edition retailed at $2.50 and the UK edition at eight shillings and sixpence (8/6). A paperback edition in the United States by Dell Books in 1954 changed the title to Murder after Hours.

The novel is an example of a "country house mystery" and was the first of her novels in four years to feature the Belgian detective Hercule Poirot—one of the longest gaps in the entire series. Agatha Christie, who often admitted that she did not like Poirot (a fact parodied by her recurring novelist character Ariadne Oliver), particularly disliked his appearance in this novel. His late arrival, jarring, given the established atmosphere, led her to claim in her Autobiography that she ruined the novel by the introduction of Poirot.

Agatha Christie's successful career foresaw the use of her eight owned houses as settings for her novels, which were Taken at the Flood, Dead Man's Folly, Five Little Pigs, A Pocket Full of Rye, and Crooked House. However, the setting for The Hollow was inspired by Francis L. Sullivan's house. Francis Loftus Sullivan was an English film and stage actor who portrayed Hercule Poirot in the plays Black Coffee (1930) and Peril at End House (1932) and also played the lead in The Witness for the Prosecution (1953), for which he won a Tony Award in 1955.

Plot summary

Introduction

Dr John Christow is a successful physician and leading researcher, although very tired and irritated by his current life. On the morning that he and his downtrodden wife, Gerda, are due to travel down to the country to weekend with friends, Christow allows his little daughter to tell his fortune with cards. When the death card is drawn, he pays no attention, but the appearance of an old flame at The Hollow seems to be the final link in a chain of fatal circumstances.

Summary

The eccentric Lucy Angkatell has invited the Christows, along with other members of her extended family, to her estate for the weekend. John Christow is carrying on an affair with Henrietta Savernake, a talented sculptor. The beautiful Veronica Cray, an old flame of Christow's, suddenly appears in the house on Saturday night to borrow a box of matches. She lives at a nearby cottage. Another cottage is occupied by Hercule Poirot, who has been invited for Sunday lunch.

John walks Veronica back to her cottage, and returns home at 3 am. The next day, Poirot is witness to a scene that seems strangely staged. Gerda Christow stands with a gun in her hand next to John's body, as it bleeds into the swimming pool. Lucy, Henrietta, and Edward (a cousin of Lucy's and a second cousin of Henrietta) are also present at the scene. John utters a final urgent appeal, "Henrietta", and dies.

It seems obvious that Gerda is the murderer. Henrietta steps forward to take the revolver from her hand, but apparently fumbles and drops it into the swimming pool, destroying the evidence. However, the pistol that Gerda was holding was not the gun used to kill John. None of the witnesses has seen Gerda shoot John. It seems difficult to build a case against any of the other potential suspects. Lucy was the next suspect, as she was seen with a gun in her basket of eggs. However, the gun was the wrong calibre. Henrietta is the next suspect, having left an unusual doodle in the pavilion around the time John was killed. When the murder weapon turns up in Poirot's hedge, it has fingerprints that match none of the suspects.

The family had deliberately misdirected Poirot, as they each knew Gerda was the murderer, and were attempting to save her from imprisonment. Gerda had taken two pistols – shooting John with one, and then planning to be discovered with the other pistol in her hand, later proven not to be the murder weapon. Immediately, Henrietta understood that John's final appeal was for her to help Gerda. Instinctively, Henrietta assumed the responsibility by dropping the gun into the pool, and later goes back to retrieve the second weapon. She hides it in a clay sculpture of a horse in her workshop to avoid the police searches. Later, she gets it handled by a blind match-seller and then places it in Poirot's hedge.

Midge Hardcastle, a less affluent relative of the Angkatells, is also staying at the house. She is in love with Edward, but Edward has always been in love with Henrietta, who had refused several of his marriage proposals. Edward comes to the realisation that Henrietta is no longer the Henrietta he once loved. He looks at Midge and realises that she is no longer "little Midge". Edward asks her to marry him. He goes for a walk with Midge, but coming to a spot where Edward has previously walked with Henrietta, Midge believes that he is still too deeply in love with Henrietta. So, she calls off the wedding.

Edward does not understand that Midge loves him too much to hold him back from Henrietta. Misunderstanding her decision, he attempts suicide by putting his head in a gas oven but he is saved by Midge. With this dramatic proof of his despair at losing her, she relents and the wedding is on again.

With the evidence apparently destroyed or suitably confused, the family believe they have saved Gerda. There is a final clue: the holster in which the murder weapon was kept. Gerda had cut this up and placed it in her workbag. Henrietta rushes to Gerda in an attempt to retrieve it and destroy the final proof of Gerda's guilt.
