The cousin-niece relationship between Louise Llewellyn-Smythe and Rowena Drake

Mrs Llewellyn-Smythe was Rowena Drake’s aunt, and that family connection shaped the inheritance arrangements that ultimately left Rowena with the estate. The will’s longstanding provision named Rowena and her husband, Hugo Drake, jointly; after a purported codicil was challenged and set aside, that original disposition took effect.

Kinship and the Original Will

Mrs Llewellyn-Smythe’s established testamentary arrangement left her money jointly to her nephew, Hugo Drake, and his wife, Rowena, who was also Mrs Llewellyn-Smythe’s first cousin and niece. If either spouse died before Mrs Llewellyn-Smythe, the survivor was to inherit. The arrangement thus joined the aunt’s family relationship with Rowena to a provision that protected the surviving spouse’s claim.

This disposition had remained fundamentally unchanged for many years. Mrs Llewellyn-Smythe had made adjustments for charities and for legacies rendered void by deaths, but the central provision for Hugo and Rowena endured. Its longevity later became important when a different document appeared to redirect the fortune.

The Codicil and the Competing Claim

About three weeks before Mrs Llewellyn-Smythe died, a handwritten codicil purportedly left the residue of her considerable fortune to Olga Seminoff, in gratitude for her devoted service and affection. This sharply departed from the familiar arrangement: the old servants received no legacies under the new document, while Olga was named as the sole recipient of the residue.

Poirot’s later explanation distinguishes that purported document from a codicil he surmised Mrs Llewellyn-Smythe had genuinely made. He believed she had discovered Rowena’s affair with Michael Garfield and, in anger, changed her will to leave everything to her au pair girl. In his account, Olga may have told Michael about the change because she hoped to marry him. The evidence therefore places the aunt–niece relationship within a conflict over both inheritance and the circumstances that may have prompted a real change of will.

Rowena’s Inheritance

The codicil that was produced was so obviously forged, Poirot explained, that a lawyer would recognize it as open to challenge. Once contested, expert evidence would lead to its being set aside, leaving the original will in force. Because Hugo had recently died, the original provision would then make Rowena the sole survivor and recipient of the fortune.

The result turns the kinship arrangement into the decisive legal mechanism of the inheritance. The aunt’s longstanding provision for her niece and nephew-in-law survived the apparent attempt to displace it; with Hugo no longer alive, the survivor clause carried the estate to Rowena.
