The same cord he had used when he strangled Andre, he now saw round the queen's neck, so tight that it made its way into her flesh: an invisible force, a Satanic impulse, urged him to strangle with his own hands the woman he had loved so dearly, had at one time adored on his knees.

The count rushed out of the room with gestures of desperation, muttering incoherent words; and as he shewed plain signs of mental aberration, his father, Charles of Artois, took him away, and they went that same evening to their palace of St.Agatha, and there prepared a defence in case they should be attacked.
But Joan's punishment, which was destined to be slow as well as dreadful, to last thirty-seven years and end in a ghastly death, was now only beginning.

All the wretched beings who were stained with Andre's death came in turn to her to demand the price of blood.

The Catanese and her son, who held in their hands not only the queen's honour but her life, now became doubly greedy and exacting.

Dona Cancha no longer put any bridle on her licentiousness, and the Empress of Constantinople ordered her niece to marry her eldest son, Robert, Prince of Tarentum.
Joan, consumed by remorse, full of indignation and shame at the arrogant conduct of her subjects, dared scarcely lift her head, and stooped to entreaties, only stipulating for a few days' delay before giving her answer: the empress consented, on condition that her son should come to reside at Castel Nuovo, with permission to see the queen once a day.
Joan bowed her head in silence, and Robert of Tarentum was installed at the castle.
Charles of Durazzo, who by the death of Andre had practically become the head of the family, and, would, by the terms of his grandfather's will, inherit the kingdom by right of his wife Marie in the case of Joan's dying without lawful issue, sent to the queen two commands: first, that she should not dream of contracting a new marriage without first consulting him in the choice of a husband; secondly, that she should invest him at once with the title of Duke of Calabria.
