# Epilogue explained — Monsieur Lecoq

> Chapter companion for Monsieur Lecoq by Émile Gaboriau.

## What happens

Lecoq, undeterred by his earlier defeat, regains his resolve after consulting Father Tabaret. He deduces that the Duc de Sairmeuse is the escaped prisoner May, and uses a starling's German accent to link Madame Milner to the duke's household. A messenger reveals the duchess's sudden death, and Lecoq secures permission from Judge Segmuller to continue his investigation. He then tricks the duke into writing a confession by impersonating Maurice d'Escorval, ultimately proving the duke's presence at the Poivrière while also establishing his innocence in the murder. The duke is acquitted, and Lecoq is promoted, adopting the motto 'Semper Vigilans.'
