A recent Reddit poll ranked
The Hallmarked Man last of the eight Strike books, and, if I recall correctly, it wasn't a particularly close vote. A lot of
THM fans insist, it's better when you re-read, and I think that is absolutely true. Then again, that's true of all of the Strike series, and RG/JKR's other works as well. Part of the huge success of the
Harry Potter series can be attributed to the details uncovered as kids and adults read them again and again. One reason I think the Strike books will never hit that level of popularity is that they are marketed squarely in the mystery category. Many adults do not read whodunnits more than once, since the thrill for them is gone once you know whodunnit.
I've read or listened to the earlier Strike books dozens of times. I've lost track of how many times I've re-read THM, but, given that I read each section at least 2-3 times when doing a detailed blog-through like the one I have just completed, it must be six or seven by now. Did THM improve on re-reading? Yes, absolutely. Did it, for me, lift itself out of last place? No, it didn't. For this summary I have re-read not the book but all of my detailed blog posts, from the Advent Adventure to the Real-time Re-read, for the purposes of summarizing what changed for me and what didn't.
