.... is Number 10, a fair sized apartment house, and this is at first a fairly routine inspection of some of its tenants which becomes more eventful in its later stages because of Robin Fay, the only youngster in the building. The Fays are one of the younger couples, and probably the nicest here; others include the twin sisters, cardiac Mrs. Lesser and spinster Miss Forsythe; Hunt Parrish, an older, overbearing man, and his wife who leads an empty, busy life as a cover for the children Hunt denied her; the Harewoods who move in under the Fays, Maud Harewood- a querulous, ailing novelist. During the course of the proceedings here, Maud's grievances against Robin mount and she recruits others in the building; there is an elevator accident, in which Mrs. Lesser dies, and Robin is again the victim of arbitrary, and imaginary, accusations.... Off to a slow start (any mechanism such as this is a delaying action), the book gains in interest as it brings familiarity with the people involved, and it is an acceptable first novel.
