There is most definitely a book and although it comprises of made-up things, it in itself will soon become a real thing. I’ve asked Harold when this might happen and as expected the answer was none too enlightening. Although the one word relating to time from the statement, was “soon”. Pointing out that the word “soon” was a relative term, did not garner a friendlier or more informative response.
Of course as “soon” as I have more clarity on the when I will post the details here. Until then just know that the `title is “The Case of the Stolen Sky-Blue Husband”, make of that what you will!
