As Time Goes By is a novel written by American author Michael Walsh, intended as a prequel/sequel to the film Casablanca.

Solly makes it clear that Lois is intended for better things, and she eventually marries a lawyer and would-be politician, Robert Meredith, whom she does not really love.

He takes Solly's money, half a million dollars, probably intended for Lois, and travels to Boston with Sam.

America has now entered WW2 and they track down Victor, who is keen to resume his part in the work of the Czech Resistance.

With North Africa once again in Allied hands, Ilsa and Rick marry and return to Casablanca with Sam.
