Honor Among Thieves is a Side Quest in Novigrad.

This is another simple quest during the main quest “Get Junior.” When you clear the casino of Junior’s men, let Rico go.

He is happy enough to promise you a reward from his boss, the King of Beggars. Simply head back to the Putrid Grove during “Get Junior” to claim a free reward. For more information about the quest and Junior, check out the page for “Get Junior.”
