The night hours in this city were the same as in any city in the world, with the peculiarity that the ground tended to retain the heat of the day for a prolonged time. In the rest of the world, the ground is always cold, sometimes becoming freezing.
Because of this peculiarity, Matt was able to get there quickly in the morning, arriving on time to save Alice. If not, it might have taken a few seconds longer, and his help could have been hopeless.
But the earth's warmth gave Matt information about what was happening as soon as he heard Alice's scream.
Tonight, the situation was no different.
Matt and Alice quickly arrived at the square that was their target. Security was not too high in this place, but powerful people occasionally walked around. Matt's targets were those.
They looked from a hidden position at the few people walking around, hoping to find a target.
