Alexei was discovered after five months by two spies sent by his father, who bribed a clerk in the Imperial Chancery.[citation needed] Unwilling to hand Alexei back to his father, Charles sent the couple to Naples. Afrosinya became visibly pregnant, and was discovered to be female and Alexei's mistress. They lived in the Castel Sant'Elmo but were again discovered by the spies. The diplomat Count Pyotr Andreyevich Tolstoy was sent to convince Alexei to return. The Count told Christine Louise, the Duchess of Brunswick Wolfenbüttel, mother-in-law to both Alexei and Emperor Charles, that her grandson, Alexei's son, could be disinherited together with his father. She pressured the Emperor to send him back.[citation needed]
