The stylish mystery from acclaimed bestseller William Boyd takes you deep into a shadow-drenched world where loyalty blurs, motives darken and every step could be fatal.

COLD WAR MOSCOW IS A PLACE SMOLDERING WITH SECRETS . . .

Gabriel Dax is on route to Russia, tasked with delivering a mysterious Blanco drawing to celebrated defector, Kit Caldwell. But Caldwell is convinced that the KGB suspects him of treachery and he wants to get out - now.

When Gabriel is ordered by his enigmatic handler Faith Green to help, he is pulled into a web of shifting loyalties and dangerous escape plans. As tensions rise and trust fractures, he is forced to confront the fine line between devotion and deception. But which will he choose?

COLD SUNSET is the third thrilling novel by William Boyd to star Gabriel Dax: travel writer, reluctant spy and accidental hero. The Sunday Times bestselling series also features GABRIEL'S MOON and THE PREDICAMENT.

Gabriel Dax returns accompanied with a new story that builds on his relationships with the characters in the first two books and especially Faith Green. A great story that will keep you guessing and at the end you'll be checking fir the next release date. Bravo!

Well worth the wait

Probably the best book in the series but the ending was a cop out. Boyd contrived an ending designed for an important aspect of the story to be continued in the next adventure whereas it demanded a conclusion and not be left hanging in mid-air, so to speak.

The ending, so frustrating after three books not to know who was the double agent especially when the author has said there won't be whether
