3. Jeffrey Epstein, the New York financier arrested on charges of sex trafficking, has a bail hearing on Monday. He’s offering his $56 million Manhattan mansion and his private jet as bond, and prosecutors are fighting back.

The impact of Mr. Epstein’s fall is still unfolding. Several states are looking into how lightly he got off after being labeled a sex offender in Florida in 2010 — which didn’t appear to faze his powerful friends in New York. The sweetheart plea deal he got then has created such a furor that the prosecutor who oversaw it — Alexander Acosta — is stepping down from his current job, U.S. labor secretary.

Did Mr. Epstein run into trouble even earlier? Our reporters spoke to students from his time at Dalton, an elite Manhattan prep school where he taught in the ’70s.
