I only had one problem with the book and that was the part where Henry’s company has some big investor they are going to do a song and dance for and then show him a patent for their cool technique. They then are going to take the patent via courier out to the patent office and apply for it. It is critical to the story that those events happen in that order, but it makes no sense to me why you would not apply for the patent just to show it off to the investor. It isn’t like applying for the patent early would make a difference to the investor—Patents take years to be approved and I don’t think anyone sees them until they get final approval. On top of that, even if someone were to see the patent, it’s a patent and they couldn’t just copy the technique, so the company still has the power to woo the investor. So that part just didn’t make sense to me.
One small plot problem wasn’t enough to make this story unenjoyable and the strength of the characters and the underlying mystery easily make this a book that I would freely recommend.
