The stranger, having finished this message, turned abruptly, and, with a quick, but silent step quitted the room, before Schalken had time to say a word in reply. The young man felt a curiosity to see in what direction the burgher of Rotterdam would turn, on quitting the studio, and for that purpose he went directly to the window which commanded the door. A lobby of considerable extent intervened between the inner door of the painter's room and the street entrance, so that Schalken occupied the post of observation before the old man could possibly have reached the street. He watched in vain, however.
