Where the Dark Streets Go — Dorothy Salisbury Davis

Father McMahon is struggling to write a sermon when a boy runs into his office. A man in his tenement is dying, the boy says, and it is too late for a doctor or the police. In the basement of the apartment house, Father McMahon kneels beside the blood-soaked man, who has been stabbed with a knife. The man asks for no absolution. He wants to talk of life, not death, and takes to his grave the identity of his killer -- and his own.

No one in the neighborhood -- not his lover or his friends -- knows the man's real name, where he came from, or why someone would want to kill him. But in his final minutes, he reveals one clue that sends Father McMahon, a cop, and a wealthy young woman down New York's dark streets, where a killer is waiting to strike again.
