How do you know Mike didn't even go as far as to announce: "I've got Jack the Ripper's diary, would you be interested in seeing it?" X
Yes, that's the statement I was relying on. But this wasn't an announcement.
My Concise Oxford dictionary tells me that the meaning of the word "announce" is to "make publicly known".
Here is the OED definition: "1. To make known as an official messenger; to deliver news; to make public or official intimation of, to proclaim (something of the nature of news)."
You asked: "why the indecent haste to announce you have Jack the Ripper's diary before you even have something to write it in?"
But Mike wasn't announcing anything. He was simply enquiring of Doreen if she would be interested in Jack the Ripper's diary, like I said.
Of course this was based on him informing her that he had the Diary and of course she would need to see it but the purpose of the initial conversation was no more than to find out if she was interested.
Is there any evidence that Doreen asked for a transcript of the Diary prior to seeing it?
And if she did, why did Mike make such an effort to acquire a Victorian diary in which to hand write extracts from the Diary for Doreen when he knew he was going to hand over to her a transcript of it?
