Hasan,one of the Byzantine operatives involved in the fake kidnapping,is captured by Jack Turner whilst spying on the house and imprisoned in his cellar. Sam slips out to see colleague Aidan who denies any treachery in Tangiers but her brief is not to rescue Hasan but to kill him before he gives away information about Sam and Byzantine. However Hasan tells her he was betrayed by the same person who sold her out and she eventually releases him but kills him after he atttacks her. 'Groebel' gives Turner a case which contains evidence of Turner's plan to buy into the Chinese-financed Upper Khyber dam but Aidan tells Sam to leave the Turner house before she gets into danger.

Lars Holm,head of KPEC,a firm out to prevent Turner's acquisition of the dam,is murdered,along with his wife,by an assassin sent by Turner. At Byzantium the word gets out that there is a mole but Keel tells the staff they are acting on behalf of a client in a bidding war with Turner. Sam accompanies the Turners to a country mansion where the bids will take place. Here she meets Bernard Faroux,with whom she had a liaison in Tangiers and agrees to tell her who betrayed her if she can get him Turner's memory stick so that he can outbid him for the dam. In the event Turner wins the bid and Sam kills Faroux after he has tried to kill her. His dying word is 'Hour-glass'. At the same time new Byzantium operative Ian gets friendly with Ryder whilst 'Hour-glass' is seen to be printed on a file in the office where Natalie, Aidan's MI6 contact,who has been sleeping with him for information,works.

Keel offers Natalie a job in exchange for naming the mole but she refuses whilst Aidan,whom Keel and Deacon Crane suspect of being the traitor,finds the link between Natalie's boss Ballard and the name Hour-glass which he used as a spy. Sam shadows Jack Carter and his accomplice Lewis Conroy and sees Turner kill Vincent Cage,an economics professor threatening to go to the police rather than help him criminally secure the money for his bid. Though suspected by Turner Sam dates Conroy and finds that Turner was planning to use a group called Kismet, who make sabotage look like natural accidents,to help him acquire the dam. Ian continues to gain Ryder's confidence running his drugs scam and agrees to plant an explosives device at the Aldwych - informing Byzantium who will test Aidan by making him disable it. Whilst Aidan rushes to the Aldwych Sam is attacked by the blank-faced assassin who killed Goebel. Written by don @ minifie-1
