On May 2, 1957, Frank Costello was shot in the lobby of his Manhattan apartment building. The bullet grazed his scalp, and his attacker fled into the night. For Costello, it was an attempted coup, a signal that Vito Genovese no longer intended to wait for power. Costello avoided police and hospitals, and instead made a single phone call.

It was not to his soldiers or his lawyers. He called Bumpy Johnson, the man who controlled Harlem. Johnson offered him shelter on one condition, that Costello come alone and follow his rules. For 19 days, Costello hid in a Harlem brownstone while Genovese’s men tore Manhattan apart looking for him.
Genovese’s search came up empty, and his attempts to send soldiers into Harlem only resulted in violence and failure. The wider underworld began to question whether Genovese could command respect. During his time in hiding, Costello developed a plan. He could not outfight Genovese, so he chose to outmaneuver him.
He would retire voluntarily, but only if the Commission adopted formal succession rules that would make assassinations unacceptable in the future. To ensure the Commission listened, Costello needed Johnson by his side. In exchange, Johnson demanded recognition of Harlem as his territory and a say in decisions that affected his interests. On May 24, 1957, Costello and Johnson walked into a Commission meeting in Little Italy.
Johnson’s presence was a direct challenge to the established order, and Genovese reacted with fury. But the other bosses, including Carlo Gambino and Tommy Lucchese, understood the stakes, a war would be costly and dangerous for everyone involved. Costello offered the Commission a deal. He would step down, Genovese would take over, and new rules would be established.
Johnson made it clear that Harlem would not tolerate a mob war, and that any spillover would be met with retaliation. The Commission voted to accept the terms. Genovese prevailed, but his hands were tied by the very agreements he had just accepted. Costello retired to Long Island and lived until 1973.
Genovese rose to power but was arrested on narcotics charges in 1959 and died in prison in 1969. Johnson became the most powerful figure in Harlem without ever joining the Commission. When he died in 1968, Gambino sent a wreath of white roses with a card that read simply, “With respect. ” The succession rules adopted that night shaped organized crime in America for the next three decades.
In Harlem, the story of those 19 days is remembered as the moment when power dynamics shifted, and a man from the streets made the city’s most dangerous bosses listen.
