The clerical work continues through the four o’clock shift change and into early evening. Six of D’Addario’s detectives are working overtime for no other reason than the case itself, giving little thought to their pay stubs. The case is a classic red ball, and as such it has the attention of the entire department: Youth division has assigned two detectives to assist homicide; the tactical section has put another eight plainclothes officers into the detail; special investigations across the hall sends two men from the career criminals unit; the Central and Southern districts each add two men from their operations units. The office is crowded with the growing herd of warm bodies-some involved in specific aspects of the investigation, some drinking coffee in the annex office, all dependent on Jay Landsman, the squad sergeant and case supervisor, for guidance and purpose. The nightshift detectives offer assistance, then take stock of the growing crowd and gradually retreat to the shelter of the coffee room.

“You can tell a little girl got killed today,” says Mark Tomlin, an early arrival from Stanton ’s shift, “because it’s eight P.M. and the entire police department doesn’t want to go home.”

Nor do they want to stay in the office. As the core group of Pellegrini, Landsman and Edgerton continue to sort through the day’s accumulated information and plan the next day’s effort, other detectives and officers newly detailed to the case gradually drift toward Reservoir Hill until radio cars and unmarked Cavaliers are crisscrossing every alley and street between North Avenue and Druid Park Lake.

Tactical plainclothes officers spend much of the late evening jacking up street dealers at Whitelock and Brookfield, driving away, and then returning an hour later to jack them up again. Central District radio cars roll through every back alley, demanding identification from anyone who strays close to Newington Avenue. Foot patrolmen clear the Whitelock corners from Eutaw to Callow, questioning anybody who looks even a little out of place.

It is an impressive parade, a reassuring performance to those in the neighborhood who crave reassurance. And yet this is not a crime of cocaine dealers or heroin users or stickup artists or streetwalkers. This is an act undertaken by one man, alone, in the dark. Even as they are tossed off their corners, the Whitelock Street homeboys are willing to say as much:

“I hope you catch the cocksucker, man.”

“Go get his ass.”

“Lock that motherfucker up.”

For one February evening the code of the street is abandoned and the dealers and dopers readily offer up to the police whatever information they have, most of it useless, some of it incoherent. In truth, the cavalry maneuvers in Reservoir Hill speak not to the investigation itself but to a territorial imperative, a showing of the colors. It announces to the inhabitants of one battered, beleaguered rowhouse slum that the death of Latonya Wallace has been marked from its earliest hours, elevated above the routine catalogue of sin and vice. The Baltimore Police Department, its homicide unit included, is going to make a stand on Newington Avenue.

And yet for all the swagger and bravado tendered on that first night after Latonya Wallace is found, there is an equal and opposing spirit in the streets and alleys of Reservoir Hill, something alien and unnatural.

Ceruti feels it first, when he walks two steps from a Cavalier on Whitelock and some fool tries to peddle him heroin. Then it touches Eddie Brown, who walks into the Korean carryout on Brookfield for cigarettes only to be confronted by a wild-eyed smokehound, half in the bag, who tries to shove the detective back out the door.

“Get the hell away from me,” growls Brown, hurling the drunk onto the sidewalk. “Are you out of your damn mind?”

And a half hour later, the spirits reveal themselves again to a whole carload of detectives, who roll through the rear of Newington Avenue for one last look at the death scene. As the car creeps down the garbage-strewn alley, its headlights fix upon a rat the size of a small dog.

“Jesus,” says Eddie Brown, getting out of the car. “Lookit the size of that thing.”

The other detectives spill from the unmarked car for a closer look. Ceruti picks up a piece of broken brick and throws it half the length of the block, missing the rat by a few feet. The animal stares back at the Chevrolet with seeming indifference, then wanders farther down the alley, where it corners a large black and white alley cat against a cinder block wall.

Eddie Brown is incredulous. “Did you see the size of that monster?”

“Hey,” says Ceruti. “I saw all I needed to.”

“I been a city boy for a long time,” says Brown, shaking his head, “and I never, ever seen a rat back up a cat like that.”

But on that night, in that alley, behind that ragged stretch of rowhouses on Newington Avenue, the natural world has been vanquished. Rats are chasing cats, just as glassine bags of heroin are thrust upon police detectives, just as schoolchildren are used for a moment’s pleasure, then torn apart and thrown away.

“Fuck this place,” says Eddie Brown, climbing into the Chevrolet.

On paper, at least, the prerogatives of a Baltimore homicide detective are few in number. His expertise accords him no greater rank and, unlike counterparts in other American cities, where detective grades and gold shields offer better pay and more authority, a Baltimore detective carries a silver shield and is regarded by the chain of command as a patrolman in plainclothes, a distinction that brings only a small wardrobe allowance. Regardless of training or experience, he is governed by the same pay scale as other officers. Even granting a homicide detective’s ability to earn-whether or not he so desires-a third or half of his salary again in overtime and court pay, the union scale still begins at only $29,206 after five years of service, $30,666 after fifteen, and $32,126 after a quarter century.

Departmental guidelines display a similar indifference to the special circumstances of the homicide detective. The BPD’s general orders manual-to the brass, a well-reasoned treatise of authority and order; to the working cop, an ever-amended tome of woe and suffering-does little to distinguish between patrolmen and detectives. The one critical exception: A detective owns his crime scene.

Whenever and wherever a body falls in the city of Baltimore, no authority exceeds that of the primary detective on the scene; no one can tell that detective what should or shouldn’t be done. Police commissioners, deputy commissioners, colonels, majors-all are under the authority of the detective within the confines of a crime scene. Of course, this is not to say that many detectives have countermanded a deputy commissioner with a dead body in the room. In truth, no one is really sure what would happen if a detective did so, and the general consensus in the homicide unit is that they’d like to meet the crazy bastard who would try. Donald Kincaid, a veteran detective on D’Addario’s shift, made history ten years back by ordering a tactical commander-a mere captain-to get the hell out of a downtown motel room, an action necessitated by the commander’s willingness to allow a dozen of his herd to graze unimpeded over Kincaid’s yet-to-be-processed scene. The action prompted memos and administrative charges, then more memos, then letters of response, then responding letters of response until Kincaid was summoned to a meeting in the deputy commissioner’s office, where he was quietly assured that he had interpreted the general orders correctly, that his authority was unequivocal and he was absolutely right to invoke it. Unswervingly right. And if he chose to fight the pending charges at a trial board, he would probably be vindicated and then transferred out of homicide to a foot post near the southern suburbs of Philadelphia. On the other hand, if he was willing to accept the loss of five vacation days as punishment, he could remain a detective. Kincaid saw the light and yielded; logic is rarely the engine that propels a police department forward.
