She has shared the missive with EW.
It is reprinted in full, below.
I realize this is overdue, and I hope you will understand why.
I am just beginning to emerge from its heartbreaking impact.
Walter died in the course of being treated for an extremely aggressive form of esophageal cancer.
It seemed to have come out of nowhere and had spread with terrifying speed.
In keeping with his wishes, he was cremated without ceremony or memorial in New York City.
Understandably, Walter wanted privacy during the course of his illness and he hoped for recovery.
He wanted to be able to return to the stage and once again perform for his fans.
He just ran out of time much sooner than any of us thought possible.
The tsunami of tributes and remembrances that have followed Walters passing has been deeply moving.
