The Secret Hours is an excellent offering in the Slow Horses world. It starts a bit slow but as soon as the first hint of connection to the Slough House world is unveiled, the pace picks up like a runaway fright train! Well done

Great read

Some writers of thrillers and espionage are good at describing action. The best, and Herron is certainly in this class, put the reader in the middle of it with only a minimal compass.

A perfectly first rate intellectually challenging spy novel in which all seemingly disparate threads are tightly woven into a thrilling conclusion which is satisfying and has the reader asking for more like this! Doug Rothkopf -Boca Raton, Fl.

What a thrilling and satisfying warp and weft of amazing characters exquisitely re-unveiled.

yes, it took half of the book to start where the point of the story is, but, totally totally worth it. I see Gary Oldman in Berlin and I feel it, the burden, the betrayal, and the heart .... the heart that makes the whole series so great... thanks, Apple, for bringing Mick and Jackson to us ...

Good story. Better if half as long. Too many useless words, sentences, paragraphs, pages. Maybe the author gets paid by the number of words??

A nice standalone story that fills in some background of certain characters but the reader may not be sure which ones for a bit. Took a while to get moving but we’ll worth it.

Loved every minute of it. I’m totally hooked on the world Herron has created. Surprising and sneaky origin story. You think it’s going one way and then… Can’t wait for more.

One of his best
