That stupid hand written letter spoiled the movie -SPOILER

I was really enjoying this movie until the final scenes when the letter was sent informing the death of the little girl.

I struggled to read the slanted hand written words, and only managed to decypher 'ill'. When the woman cried I presumed the girl had died but I wasn't sure.

Later we saw the girl wasn't there, but I was still puzzled what had gone on.

It was only Cary Grant telling us in very mixed-up language that the girl had been ill and died suddenly.

I thought this was a very bad moment in the movie. What should have been done was when the woman was reading the letter, a voice of the 'mother' should have been heard reading out the words too.

What do others think?
