For the second morning running London awoke to the news of a spate of bombs exploding.

While the emergency services phones were busy taking calls and directing fire appliances and police officers, so an underground network was also waking and taking action.

In the downstairs bedroom of 221B Baker Street two sleeping figures were startled awake as John's phone belted out a rock classic.

Scrabbling for his jeans John dragged the offending item out of his pocket and answered it, his voice rough with sleep.

Switching on the bedside lamp Sherlock watched as the shorter man stood, pulling on clothes as he listened and as the call ended Sherlock could see the thoughts racing around his head.

"Get dressed, we need to get over to Greg's place."

"He's back?" Sherlock pulled shirt and trousers on with quick smooth movements.

"No, more bombs." Walking out of the room John headed to kitchen and rummaged in a draw, grabbing a set of keys that were hidden at the back before returning to the hall to put on shoes and Jacket.

Sherlock was waiting .

"We need to get whatever it was Sally Donovan left hidden before Scotland Yard realise he's missing and turn the place over."

Downstairs Sherlock hailed a passing cab, and holding the door for John followed him into the back.
