Matt twisted as he ran, putting his already abused shoulder to the third story glass window and felt it explode out from under him. Behind him, he left Cole with a half-assed apology and the muffle sounds of explosions roaring through the building. As he fell, a rushing heat behind him told him that the explosions weren't confined; rather, the gouts of flame and smoke seemed to be consuming the third floor of the headquarters building. Matt fell, sensing below him that his luck was holding in the form of a taxi cab.
Please don't pull away!
He hit hard, bruising ribs as he dented the taxi's roof and rolled off. Matt hit the pavement running and sprinted for the Thames. It would be his only escape. No doubt that once things were settled up top, there would be teams hunting for him. A short fence kept passersby from crossing into the river. Matt vaulted it easily and arced into a clean swan dive. Once under the murky water, he was radar blind. Sound traveled faster in the dense water, so his radar was coming back muddled and compressed. It didn't matter. he was a veteran swimmer canoeist and could navigate by sound in the river if he had to. Theoretically.
He struck out with strong strokes deep under the surface of the water, headed down river. He could swim concealed like this for five minutes before he needed a breath. The trick was to cover as much ground during that time as possible. Once he surfaced, the smoke rising from Homeland Defense's headquarters was a smudge a half mile away. Matt couldn't see the smoke, but the wail of emergency vehicles was distant and tinny. At a more relaxed pace, Matt continued swimming until he found a series of drainage pipes. They smelled like sewage, but they'd suit his purposes. He approached cautiously and carefully pulled back the corner of the mesh that guarded the mouth of the pipe, then clambered inside and replaced the grating. From the outside, there was no visible evidence of his passing.
Mission of escape accomplished, Matt brought his knees to his chest and leaned against the wall of the pipe and fell asleep. Exhaustion dropped him quickly into somnolence, but adrenaline kept it a light sleep. If anyone approached, he'd hear them.
