The Queen household, an apartment on West 87th street in New York City shared by the Queens father and son, also contains a houseboy named Djuna, at least in the earliest novels and short stories. This young man, who may be of Roma origin, appears periodically in the canon, apparently ageless and family-free, in a supporting role as cook, receiver of parcels, valet, and as occasional minor comedy relief. He is the principal character in some, not all, of the juvenile novels ghost-written by other writers under the pseudonym Ellery Queen, Jr.
