In a case that was termed "stranger than fiction",[4] at the last moment of the cross examination of Walsh's husband in court it was discovered that three years prior to marrying her, he had wedded another woman.

At the trial Euston admitted that when walking along Piccadilly he had been given a card by a tout which read "Poses plastiques.

[6] The final defence witness, John Saul, was a male prostitute who admitted to earning his living by leading an "immoral life" and "practising criminality".

[8] H. Montgomery Hyde, an eminent historian of homosexuality, later wrote that there was little doubt that Euston was telling the truth and only visited 19 Cleveland Street once because he was misled by the card.

[9] However, Robert Cliburn, a young man who specialised in blackmailing older homosexual men, told Oscar Wilde that Euston was one of his victims.

[10] In 1894, while presiding at a police court in Towcester, Euston sentenced a man to one month's imprisonment for stealing a cake valued at 3d from a shop in the village of Blisworth, then part of the ducal estate.

In court, Euston stated the loans had been raised to assist the solicitor Arthur Newton out of "simple friendliness" while he had been acting for him.
