 Occleshaw saw irregularities in the available information about Larissa, such as the different ages given on her marriage certificate, her tombstone, and her death certificate, the differences in the names given for her, the conflicting stories about her background, and Tudor's inexplicable income and return to the 3rd Hussars and promotion in rank following Larissa's death.There was no record of a woman named Larissa Haouk entering England between 1918 and 1923.Occleshaw showed portraits of Grand Duchess Tatiana Nikolaevna, along with portraits of unrelated women from the same period, to people who had known Larissa.
