After several more years of being the namesake of a man who was then famous for starring in the most sensational tabloid stories of the era, Don Jr. graduated from college, moved to Colorado and got a job bartending. Ivana said she made her disapproval clear by “cutting him off” until he gave up, returned to New York and joined the Trump Organization.

Do you see what I mean? It’s a miracle the man is walking and taking nourishment. I will never attack him again. Well, except for the elephant hunting.

A lot of “Raising Trump” is Ivana bragging that the children were never spoiled — unlike those Kardashians. There’s a lot about her glamorous wardrobe and triumphs as a C.E.O. in the family businesses. (“My version of helicopter parenting was to bring the kids to work with me in the Trump chopper.”)

And you just keep plowing on because you figure sooner or later she’s going to get to The Affair.

Finally, it’s 1989 in Aspen. A young woman comes up to Ivana and says: “I’m Marla and I love your husband. Do you?”

What followed was perhaps the biggest sex scandal in American history. O.K., I’m totally exaggerating. (Remember that whopper in the 19th century with Grover Cleveland’s illegitimate child?) But the Donald-Marla-Ivana story was unusual in that at the time, nobody involved in it was all that important. Trump was a celebrity real estate developer, but there were plenty of equally rich and glamorous figures in New York, many of them having adultery issues of their own.

The difference was that Trump pushed the story, calling his allies in the media with new tidbits or lines of defense. It was as if Grover Cleveland had press agents trying to make sure his side of the love-child scandal was in a headline every day.

You will not hear anything about that angle in Ivana’s book. In fact, once the affair comes center stage, you hardly hear anything about Donald at all. He seems to be a sort of passive bystander. (“After the showgirl got pregnant and had a daughter, Donald married her.”)
