Struggled through the audio book; the first half was quite interesting and intriguing to me as I met the different characters. However, the last half became very slow and confusing. It may be me, as I listened in snippets here and there. I never really understood the "who" and "why" of the traitor. I wish someone would write a nice review with spoilers to illuminate me! I'll try another John Creasey work, but found this one slow and, as another reviewer stated here, "Dull."
