From behind the limited concealment of a tree, Caruso watched Mortimer trudge up the street. He’d seen him pass an envelope, but the guy he’d passed it to didn’t remotely resemble the sort of guy he’d have taken for Batman. But that didn’t matter, Caruso said to himself. If this fuck was Batman, and the Big Assignment came his way, then it didn’t matter if the guy looked the part or didn’t look the part. Either way, the guy was history.
Now, as he fell in behind Mortimer, following him at a distance, he wondered just how many guys Mortimer would see during the night, how long the list he’d have to whittle down, eliminating one guy at a time, until he knew which one Batman really was.
Mortimer reached Fifth Avenue, then headed uptown again. It was a clear, cool night, but as far as Caruso was concerned, the air’s crisp clarity did nothing to recommend a long nocturnal stroll up the blue spine of Manhattan. What if Mortimer were a drunk? Caruso asked himself. What if the poor hopeless bastard was one of those guys who spent his nights going from bar to bar but always managed to appear sober the next morning. Caruso considered this possibility, then instantly believed that Mortimer was precisely this kind of guy. From that unappetizing conclusion, he imagined himself tailing his black-hatted quarry from one gin mill to the next as the hours dropped dead one by one, and dawn at last broke over the bleary face of the city.
But as Mortimer continued north, he seemed hardly to notice the taverns he passed. Instead, he appeared entirely lost to the world around him, hardly noticing the speeding traffic or his fellow pedestrians. When an old woman’s small white dog leaped at him, snarling and straining at the leash, he seemed barely aware of it. He didn’t flinch away or alter the pace of his forward momentum but only sailed onward, holding to his course like a battered old steamer churning its way home.
At Nineteenth Street, Mortimer turned westward, his gait now so weary and unsteady he seemed perpetually jostled by a rude, invisible crowd. The signs from the bars did not beckon to him. He passed them like strangers, wobbling on through the nearly deserted street until he reached a building whose address Caruso could clearly read: 445 West 19 Street.
It was a five-story brownstone that looked carefully maintained. Two black wrought-iron railings led up seven cement steps to a polished wooden door. Four windows faced the street, and there were terra-cotta flower boxes in each of them. Some kind of greenery rose from the boxes, but there were no flowers. There was a large brass knocker on the door, but Caruso noted that Mortimer pressed a small buzzer instead, then waited until the door opened.
