Druitt's father died suddenly from a heart attack in September 1885, leaving an estate valued at £16,579 (equivalent to £ today). In a codicil, Druitt senior instructed his executors to deduct the money he had advanced to his son from the legacy of £500. Montague received very little money, if any, from his father's will, although he did receive some of his father's personal possessions. Most of Dr Druitt's estate went to his wife Ann, three unmarried daughters (Georgiana, Edith and Ethel), and eldest son William.
