Haven't seen an update, so I tried something else. I have a special spread I created that blends horary astrology meanings with tarot cards. I ran that today to see if it would give any additional insights.
First I randomly picked a significator for the central position from the court cards of a second deck, with the idea that its "facing" might give a nod (literally) toward which direction to search. But I got the King of Swords, who is facing outward and barely inclining his sword to the East (King's right side). Normally, the facing-out posture would reflect South (upright) or North (reversed). Then I laid out 8 cards counter-clockwise in a circle around it from the East (left-most) position. In the East position sat the upright 7 of Swords. All of the other cards showing possible directions (save the Knight of Swords in the West - more about that later) were reversed, which I take as a preliminary "No," so I interpreted the leaning Sword of the King and the upright 7 of Swords to indicate a "due East" orientation. Both of the cards being Swords, it seemed like a good "signature" for a book. The figure in the 7 of Swords looks like he's "stealing away" with five purloined swords, out of the area in an easterly direction. The Knight of Swords (score another one for "book") appears to be rushing onto the scene from the West, perhaps showing that your hiding of the book was a hurried event.
On the face of it, this seems to be showing that the book has left the immediate premises, going East, while the "guest" you mentioned came in from the West. It makes me wonder whether trash disposal, or a place where trash might be gathered for disposal (like a garage bin or dumpster), lies toward the East. The Seven shows a couple of things: it is probably more "far" than "near" in its relation to you, it is probably with several or quite a few other items, and it is in fair-to-poor condition; also that the search will be a moderately lengthy one. Swords suggest the book is near a window, or possibly with "cutting tools" that you might find in a work area.
If it somehow went out with the trash, it's probably gone for good. If the trash is still in a "holding area," you might widen your search (but it might be damaged if you find it).
Again, good luck!
ETA: One thing I forgot to mention. A King in the center of the spread can show that an older male - husband (or male partner), father or grandfather - has the lost item. But I see that as a long shot.
