The Dead are Blind

The Dead are Blind is a 1937 Australian novel by Max Afford featuring his hero Jeffrey Blackburn. It was the third Jeffrey Blackburn novel.
Afford wrote the book in two months. As with the first two Afford novels, Dead are Blind was published in London before Australia. It was the third novel under a three-book contract Afford had with John Long.

Premise

But when the leading actress collapsed, seemingly with heart failure, he found that chance had led his steps into one of the most intriguing and bewildering crime cases of the year."
