Bertrand did not long survive him.

He actually lost his reason when he heard of his father's death, and hanged himself on the prison grating.

Thus did the murderers of Andre destroy one another, like venomous animals shut up in the same cage.
Catherine of Tarentum, carrying off the treasure she had so gained, arrived at the court of Naples, proud of her triumph and contemplating vast schemes.

But new troubles had come about in her absence.

Charles of Durazzo, for the last time desiring the queen to give him the duchy of Calabria, a title which had always belonged to the heir presumptive, and angered by her refusal, had written to Louis of Hungary, inviting him to take possession of the kingdom, and promising to help in the enterprise with all his own forces, and to give up the principal authors of his brother's death, who till now had escaped justice.
The King of Hungary eagerly accepted these offers, and got ready an army to avenge Andre's death and proceed to the conquest of Naples.
