Seventeen-year-old Dickory Dock, an art-school student in Greenwich Village, answers an ad for a job as a painter's assistant at Number 12 Cobble Lane. The painter, Garson, hires her; in her duties of cleaning paintbrushes and answering the door, she becomes involved in Garson's mysterious affairs, as well of those of his downstairs neighbors.
A clever mystery with shifting identities. The reader is given all the clues necessary to solve the underlying case, but even the questions are hidden.
