Forged-Codicil Plot to Frame Olga

The Forged-Codicil Plot to Frame Olga is a scheme to manipulate an inheritance by making Olga Seminoff look like the author of a fraudulent codicil. Its central trick depends on two documents being mistaken for one: Poirot distinguishes an apparently genuine codicil that redirected the estate from a conspicuously forged document submitted for probate. The forgery was designed not to survive expert scrutiny, but to cast suspicion on Olga, remove her as a witness, and leave Rowena Drake positioned to inherit under the earlier will.

The Inheritance and the Two Documents

For many years, Mrs Llewellyn-Smythe’s testamentary arrangements had followed a consistent pattern. Charitable bequests and legacies to old servants might change, but the bulk of her fortune went jointly to her nephew, Hugo Drake, and his wife, Rowena, who was also Mrs Llewellyn-Smythe’s cousin and niece. If either spouse died first, the survivor inherited. That provision gave the old will decisive force once Hugo had died.

The document that first drew attention was presented as a codicil made about three weeks before Mrs Llewellyn-Smythe’s death. Unlike her previous documents, it had not been drawn up by her regular solicitors. It was said to be in her handwriting, reduced the number of charitable bequests, omitted legacies to the old servants, and left the residue of her considerable fortune to Olga in gratitude for her devoted service. The change was so unlike the established pattern that it immediately appeared remarkable.

There was also a separate account of Mrs Llewellyn-Smythe making a document in front of Harriet Leaman and a young garden worker, Jim. According to Leaman, Mrs Llewellyn-Smythe sent Olga out of the room, covered the upper part of the paper with blotting paper, wrote several lines with her scratchy pen, signed, and asked both witnesses to write their names and addresses. The account establishes that Leaman witnessed a document being written and signed; it does not establish that this was the forged codicil later submitted for probate.

How the Forgery Created Suspicion

The submitted codicil was not authenticated by Leaman and Jim. When Poirot checked with the solicitor, he learned that its witnesses were Mary Doherty, a former servant who had died, and James Jenkins, who had gone to Australia. That discrepancy matters: a witness’s memory of seeing a document signed cannot by itself establish that the document later offered for probate is the same one.

Handwriting experts found that the submitted codicil bore only a faint resemblance to Mrs Llewellyn-Smythe’s hand and was a complete forgery. Olga nevertheless made a convenient suspect. Mrs Llewellyn-Smythe disliked typewriters and often had Olga write personal letters, copying her employer’s handwriting; on some occasions Olga had even signed Mrs Llewellyn-Smythe’s signature. Her experience supplied a ready-made explanation for the forged writing, and the apparent benefit to Olga made the accusation seem plausible. Earlier discussion of the affair had already raised the possibility that Olga could have produced the document.

The law’s timing helped the scheme. The solicitors identified the forgery quickly, and proceedings were to be taken to contest it, but the usual delay meant that the case would not immediately reach court. During that interval Olga lost her nerve and disappeared. In Poirot’s reconstruction, the conspirators did not need her to be convicted or prosecuted: it was enough for the forged document to make people suspect her. Her disappearance could then be read as further evidence of guilt, while also removing someone who knew about the other codicil.

The Intended Legal Outcome

The forged document was meant to fail. Because it was so plainly defective, Poirot reasoned, a lawyer would challenge it and handwriting experts would establish its falsity. The challenge would undo the codicil and restore the original will. With Hugo recently dead, Rowena would then receive the fortune as the surviving beneficiary.

This was the plot’s essential legal misdirection. The forgery seemed to be a clumsy attempt to secure the estate for Olga, but its obviousness was useful to the people behind it: its expected rejection would return the inheritance to Rowena. The forgery therefore had a double purpose. It created a conspicuous accusation against Olga while arranging for the earlier disposition, favorable to Rowena, to prevail. The suspicion generated by the document and the inheritance produced by its failure pointed in different directions only if the genuine codicil was overlooked.

The Genuine Codicil and the Conspiracy

Poirot’s explanation treats the document witnessed by the cleaning woman as a real codicil, distinct from the fake submitted for probate. Its precise contents are not independently established in the account, so his reconstruction remains a surmise: he believes Mrs Llewellyn-Smythe discovered that Michael Garfield and Rowena were having an affair, probably before Hugo died, and reacted by leaving her estate to the au pair girl. He further suspects that Olga told Michael about the change because she hoped to marry him.

On Poirot’s account, Michael and Rowena needed Olga removed because she knew of the genuine codicil. They also needed her to appear responsible for the forgery. Michael allegedly paid Lesley Ferrier to produce a similar document after Mrs Llewellyn-Smythe had hidden the original. Poirot rejects Michael’s account of a love affair or arrangement between Lesley and Olga as an unconfirmed story. Instead, he concludes that Michael was courting Olga, encouraging her to keep quiet with the prospect of a future marriage, while treating her coldly as a person who could be made the scapegoat.

The false accusation was joined to lethal violence. Poirot concludes that Olga was killed once the plot required her silence and that Lesley was killed after his involvement in producing the forgery. Lesley’s stabbing was made to resemble a gang attack or an attack by a jealous woman, but the knife found in the well corresponded closely to his wounds. The document was thus not an isolated fraud: it helped disguise a succession of crimes by making Olga appear to be the dishonest party and Lesley’s death appear to have another explanation.

Exposure and Significance

Olga’s disappearance did not settle what had happened to her. Poirot knew her body must be hidden nearby but did not initially know where. Miranda Butler’s questions about a wishing well, and Michael’s refusal to take her there, directed attention to the possibility that the well mattered. Mrs Goodbody’s recollection of the nursery rhyme about a cat in a well confirmed Poirot’s suspicion; Olga’s body was found in a well in Quarry Wood, on an incline not far from Michael’s cottage. Poirot also considered that Miranda might have witnessed either the murder or the later disposal of the body, while Rowena and Michael feared that someone had seen something without knowing who it was.

The plot’s force comes from the difference between documentary appearance and evidentiary identity. A person may witness a signature without witnessing the signing of the document later produced; a handwriting resemblance may be explained by practice without proving authorship; and a forged instrument can have its intended effect even when it is legally worthless. Here the counterfeit’s failure was part of its design. By disentangling the forged codicil from the genuine one, Poirot reveals how inheritance, suspicion, disappearance, and murder had been arranged around the same deception.
