A Famous Necklace

Jewels in Plain Sight
Linnet’s treasured pearls
Linnet wears a remarkable necklace worth a fortune and treats it as an ordinary part of her life. She says it is insured, which leaves her relatively unconcerned about theft.
An opportunity for access
The necklace’s visibility and value make it tempting to thieves. Its history with Linnet also gives anyone who has handled it a chance to prepare a convincing copy.
The Necklace Disappears

A Second Crime
The empty bedside table
Louise says Linnet placed her pearls on the table before going to sleep. Poirot finds them missing after the murder and begins to consider robbery as a possible motive.
An unsatisfactory explanation
A thief who murdered Linnet would have difficulty escaping detection aboard the steamer. Poirot questions whether the disappearance and the killing truly belong to one plan.
A Necklace Returned

The Nurse Produces the Pearls
A confession about kleptomania
Miss Bowers gives Race a necklace taken by Marie Van Schuyler, explaining that the older woman has a habit of stealing jewelry. The apparent recovery seems to resolve the missing-property problem.
A more troubling object
Poirot recognizes that the returned necklace is an imitation. Its presence creates new possibilities: a second theft, an earlier substitution, or a story invented to conceal another crime.
Tim’s Hidden Rosary

The Real Pearls Concealed
The substitution exposed
Poirot connects the false necklace to Tim Allerton and Joanna Southwood’s jewelry scheme. He concludes that the genuine pearls are hidden inside the carved beads of Tim’s rosary.
A crime beside the murder
Tim admits stealing the pearls but insists he did not kill Linnet. His theft explains the missing necklace without explaining the murder, forcing the investigators to keep the two crimes distinct.
The False Necklace Discarded

Ending the Jewelry Scheme
Return of the original
Tim agrees that Poirot has located the real pearls. He puts them back in the box and disposes of the imitation by throwing it into the Nile.
A separate resolution
The necklace mystery ends through confession rather than through a discovery of the murderer’s motive. The distinction prevents Tim’s theft from obscuring the conspiracy behind Linnet’s death.
