"Gerard Doyle performs this stand-alone dispatch from Mick Herron’s cynical “spook street” world with such dry resignation that it is often laugh-out-loud funny... Doyle’s vocal control is masterly, his pacing, range, and attention to detail a perfect match for Herron’s, which is highest praise." 
- Audiofile Magazine

It’s another superb outing for Duffy, made all the more so by Gerard Doyle, who has narrated the entire series so far and has, for me, become inextricable from its festive, sardonic humor. A genius at accents of the British Isles, he delivers a genuine-sounding Ulster accent among others, and excels in acerbic asides and conversational exchanges, each character possessing an identifying manner and voice.

“Gerard gives the characters fullness, creating just the right visceral momentum through some of the action chapters.”
- Frank Beddor, Author of Seeing Redd
 
"Doyle’s delicate, world-weary voice is the perfect vehicle for Herron’s espionage fiction, which manages to be witty and twisty even as it second-guesses the cleverness and heroism of spies themselves." 
- Laura Miller, Slate Magazine
