The intrusions / Stav Sherez.

When a distressed young woman arrives at the station claiming her friend has been abducted, and that the man threatened to come back and "claim her next", Detectives Carrigan and Miller are thrust into a terrifying new world of stalking and obsession. From a Bayswater hostel, where backpackers and foreign students share dorms and failing dreams, to the emerging threat of online intimidation, hacking and control, the duo find themselves in the middle of a complex and disturbing case involving a highly intelligent and ruthless killer who engages in a refined form of torture and murder. Under scrutiny themselves, and with old foes and enmities resurfacing, how long will Carrigan and Miller have to find out the truth behind what the two women have been subjected to?
