John Purkiss: Tundra (John Purkiss, #4) (ePub)

John Purkiss, the Ratcatcher, returns in his most dangerous mission yet...

A retired British Intelligence operative, Frank Wyatt, has surfaced as a research scientist at a remote outpost in the bleak, inhospitable tundra of north-eastern Siberia. But there's strong evidence that Wyatt was a double agent working for the Soviet KGB and its successor organisation, the FSB... so what is he doing at Yarkovsky Station?

John Purkiss is sent to investigate. 

In the guise of a journalist, Purkiss arrives at the research station and finds himself among an eccentric group of personnel, many of whom appear to be harbouring secrets. His attempts to delve more deeply are met with increasing degrees of suspicion, hostility and outright obstruction. And during a field excursion into the tundra, an attempt is made on Purkiss's life. 

When a member of the station's personnel is brutally murdered, and the communication links with the outside world are sabotaged, Purkiss and the rest of the staff are trapped hundeds of miles from human contact, in an atmosphere of growing mistrust, intrigue and danger. After more killings, and with a deadly team of Russian military closing in on the station with orders to terminate both its operations and its personnel, Purkiss is forced to confront not only his human enemies, but also the terrible, primal power of the tundra itself... 

TUNDRA is the fourth thriller in the the highly acclaimed John Purkiss series, which began with RATCATCHER and continued with DELIVERING CALIBAN and JOKERMAN.
