This may be a strange question, but how would you phrase a condolence note to someone who you practically suspect of complicity in the dead person's death?
I shouldn't go too far into this story, as it isn't mine, but to simplify, "Anastasia" and "Cuthbert" were unhappily married. In the process of leaving Anastasia, Cuthbert died of a heart attack. Cuthbert's old family friend (to clarify, absolutely non-romantic friend), "Matilda" was informed of this, and more, by Cuthbert's grown children. Anastasia has just sent Matilda an email, apologizing abjectly for not informing her of the death before the funeral ("I must humbly apologise for this terrible loss of memory..ask for your forgiveness for what is unforgiveable"). Matilda does not like Anastasia, and thinks that Cuthbert would still be alive if it were not for her various actions, especially given Cuthbert's known heart condition.
How should Matilda politely reply to this email?
Not Matilda
