‘Cairo–Alexandria train,’ the Signmaker said, ‘find and zoom in.’

In a split second, the HoloSpace showed a satellite image of the train racing through the Egyptian night. There were two figures on the roof of a middle carriage.

‘Acquire heat signatures and zoom.’

The images showed Yasmin backing away from Jackal’s gun as the countryside whizzed by. The Signmaker had saved the girl once, sending that AutoDrive car into the cop’s motorbike back on the Cairo bridge, but that effort would’ve been in vain if she died now.

There were only seconds to do something—and it would have to be something drastic.

‘Access signals and rail network.’

The command went out and a moment later the Signmaker had control of the Cairo–Alexandria Express from the security of the golden-lit secret headquarters.

‘Digitise voice to Yasmin Adib. Disengage Yasmin Adib silent phone function.’
