Scotland Yard was in turmoil.
Gregson and Dimmock had been contacted and deployed to two of the bomb sites, but the Control Room operator had been unable to get a response from either Greg Lestrade or Sergeant Donovan.
Checks with members of their team gave them no answers, Greenaway hadn't seen Lestrade since the previous evening at the river, and as far as everyone understood Sally was working with Woolwich MIT, but the control Room supervisor was concerned. Neither of them was answering their home phones, and their mobiles appeared to be dead.
It was unusual enough for the Detective Chief Inspector to send a car round to each of their homes, and assign another Detective Inspector to make preliminary enquiries at the scene of the third explosion.
Three officers climbed out of the squad car and moved through the door to the flats, choosing to take the lift instead of running up the stairs.
They gained entry by forcing the lock, and soon they saw the signs of a struggle in the spare bedroom. With a cursory glance around the rest of the flat they called it in as a crime scene.
One officer stayed outside the flat, the others returned to their car. Neither of them noticed the two men standing watching in the shadow of a nearby building.
