Mrs Oglander (The Unbreakable Alibi)

In the Tommy and Tuppence short story The Unbreakable Alibi, Mrs Oglander and her husband were having supper at the Savoy seated at the table next to Una Drake and Jimmy le Marchant one Tuesday, Tommy and Tuppence were investigating Una's claim that she was at that same time in Torquay. Jimmy le Marchant had told the Beresfords that the Oglanders were seated next to them and could corroborate Una's story. Tuppence found Mrs Oglander in the phone book and called on her pretending to be the representative of a new illustrated paper researching the "smart" supper party at the Savoy. Mrs Oglander confirmed that she and her husband were at the Savoy on the Tuesday in question and that Una was indeed at the next table.

Mrs Oglander is a character in LWT's 1983 adaptation of the story (Episode 7 of Agatha Christie's Partners in Crime) but she does not appear onscreen and is not cast. Tuppence does not go to see her in this adaptation. The Beresfords sent Albert Batt to question her instead and he reports his findings to them.
