Identify this book!

A reader emailed a book description, hoping I'd recognize their long-lost teen novel. 
 

Quick question, have you come across or do you remember a book from the 1950s set at a college campus within the fraternity/sorority system? The most significant moment from the book is the "golden couple" driving off down fraternity row and getting in a car accident that kills them both. There's a similar moment in Anne Rivers Siddons "Heartbreak Hotel" but it's not that book.

I couldn't help; it doesn't sound familiar to me.  Anyone else?
