When our story begins, Biff is spending a very long night people-watching at the New York Café. He takes a special interest in both Mick Kelly and Singer.
After Jake gets into a fist-fight, Biff hooks him up with Singer so Jake has a place to crash. Then the next day, he helps Jake find a job. Nice enough for you?
Unexpectedly, Biff's wife Alice dies in the fall.
He spends time with his sister-in-law, Lucile, and his niece, Baby, on the day of the funeral, and he continues to see them regularly afterwards.
Biff starts to redecorate his apartment and begins using various feminine toiletries, like perfume. He also starts making window displays at his restaurant.
Biff spends most of his time pondering life's mysteries and more specifically, the mystery of Singer.
In usual nice-guy fashion, he writes a letter on Willie's behalf after Willie gets arrested. And continuing the streak, he later supports Lucile and tries to act as a mediator after Bubber shoots Baby. He even goes with the Kellys and Singer to track down Bubber after he runs away.
Biff hires Harry Minowitz to work in the Café and he handles Singer's affairs after his suicide.
After reaching out to Jake, Biff is the last person that Jake sees before he leaves town.
At the end, Biff continues his deep thoughts: he ponders whether or not he should leave his Café open, he feels that his love for Mick is over, and he wonders about his future.
