Mr Agrodopolous

In the novel Crooked House,  Mr Agrodopolous is the elderly Greek proprietor of the Delphos restaurant. As a young man he had been helped and befriended by the wealthy Aristide Leonides. Agrodopolous had aways felt grateful and indebted to his friend and benefactor while Leonides apparently had great trust in him. Some time before Leonides died, he left a sealed envelope with Agrodopolous. Agrodopolous was to forward the envelope to the solicitor Mr Gaitskill should he learn that Leonides has died. Accordingly, shortly the murder of Leonides, Gaitskill received the envelope from Agrodrpolous. It turned out to be Leonides' missing will.
