Leaving aside the fact that Orton was the size of like three Sir Rogers, another thing that undermined his blatant attempt to claim a dead man's fortune was his voice: Tichborne grew up in France, meaning he spoke English more or less like Inspector Clouseau, while Orton couldn't understand a word of French and had a thick Cockney accent that was obvious even from his brutally misspelled letters to his "ol' mum." Lady Tichborne took one look at the uneducated, unscrupulous scammer trying to profit from her grief and told him to eat every dick and get lost.The Success:
Wait, no: She told him, "Welcome back, Roger!" The old lady was so desperate to believe that her son had returned from the dead that, discarding the nearly 200 pounds of evidence standing in front of her, she mistook Orton for the guy she had given birth to. And, of course, once Lady Tichborne declared that this was Sir Roger, other members of the family followed suit.
"It's him! I'd recognize that nose anywhere!"
Orton's time as a member of the Tichborne clan would have lasted a lot longer if Lady Tichborne hadn't croaked two years later, sending her heirs (real and pretend) into a long legal battle for her estate. In 1872 Orton lost the case and was prosecuted for perjury after it was determined that he lacked a couple of distinctive body tattoos Sir Roger had (efforts to locate them between the folds of his skin claimed the life of a constable). Still, most of the common classes continued to side with poor "Sir Roger" for years.
