|But not that sort of daisy.|
In my 'day job' I work with a lot of material from archives. Which means places like the National Archive at Kew in London send me e-mail newsletters. Which sometimes include details of the offering from the on-site bookshop. I think that was where I saw Roy Berkeley's A Spy's London. It might have been something from the British Library bookshop. You can see where this is going, can't you? Temptation, right there in the in-box.
I resisted the physical book. (Sorry, whichever bookshop sent me the e-mail. I'm sure I'll make it up to you next time I visit.) But eventually I succumbed to downloading to the Kindle. Research, It's called research. But the book writing kind not for the academic work.
I didn't realise until I dipped into it that the book is actually a series of walks around London, looking at places made famous (or infamous) by connections with espionage. I probably didn't read the blurb properly.
I'm now very much enjoying intermittent armchair walks around areas of London that I know quite well, and I'm learning a lot. And also finding out that there is a lot more to learn. Which in due course will probably mean more books. See what I mean, about daisy chains? One thing leading to another. I was delighted to find that the book has information that will be useful for a number of the ideas that I have in my head - a time slip set partially in World War Two and the contemporaries that now have their own log book.
But If I hadn't been on the mailing list for the Archive/Library bookshop I probably would never have found it.
Daisy chains. Or possibly serendipity?
