A shipping disaster in the nineteenth century has stranded a man and woman in the wilds of Africa. The lady is pregnant, and gives birth to a son in their tree house. The mother dies soon afterwards. An ape enters the house and kills the father, and a female ape takes the tiny boy as a replacement for her own dead infant, and raises him as her son. Twenty years later, Captaine Phillippe D'Arnot discovers the man who thinks he is an ape. Evidence in the tree house leads him to believe that he is the direct descendant of the Earl of Greystoke, and thus takes it upon himself to return the man to civilization.
In the distant future the world is in the grip of another ice age. A city originally built to house five million people is now in its death throes as the relentlessly advancing glacier is slowly crushing the metropolis's steel infrastructure. The relatively few surviving fur-clad inhabitants, perhaps thousands, perhaps only hundreds, drift aimlessly in their grim, drab world, awaiting their inevitable fate as they try to survive from day to day with scavenged firewood and minimal diet. Their only solaces are booza, an alcoholic drink distilled from moss, and Quintet, a seemingly innocuous board game for six players. The only other surviving mammals are roving packs of hungry rottweilers which roam the city's corridors and quickly dispose of the remains of the dead. Newly arrived from the south is Essex with his pregnant wife Vivia, seeking shelter in the doomed city, only to find it populated by people middle-aged or older. They had supported themselves by hunting seals, but now that the last of the aquatic mammals has been killed off, they seek shelter in the apartment of Essex's brother, a renowned Quintet player. The new arrivals quickly learn that the game has a more sinister side.

The Loveland Dance Hall is one of the tenants of the Vanderkill estates. To reassure his aunt Sophie, Vanderkill visits Loveland to determine whether it is as disreputable as Sophie suspects.

There she meets Panama Canal Kelly, a former suitor who now owns a silver mine. Her plans for divorce and quick remarriage are complicated when Vanderkill arrives to confront her.
On the eve of his second marriage, Norman Overbeck learns that he is the father of his ex-wife's new-born baby, as she was pregnant when they got divorced. After becoming engaged to two women, in a scheme to get the baby, he returns to his former wife.
