Peter Guillam finds himself obliged to revisit a particularly painful old case, one which is related intimately to the events in Thje Spy Who Came In From The Cold, looking doiwn the barrell of a Parlamentary Inquiry and even prosecution.

Really, really good. Intricate, complex, filled with the agonies of making wretched sacrifices for a cause that may not exist. Tom Hollander narratyes, exquisitly.
