The gondolier's house

It was the day when 6 of my most mysterious and dangerous subjects, Il Mister, The Fox, The Muse, El Guapo, Eleonora Krane and Jackie'O Can had a secret meeting in Venice. A new, seventh member would be introduced to their circle. All I had to investigate was when and where the meeting would take place. My intuition didn't fail me… As I was walking around, I found myself looking at a house. A gondolier's mother obviously had just finished her laundry, I thought,  because 7 gondolier's shirts were hanging by the rope… I knew I was in the right place the right time.
