Spring has come to Detroit's Sugartown enclave, and Amos Walker would like to feel kindly toward the human race. Unfortunately, his first case of the new season immediately leads him into trouble among the Polish settlers of neighboring Hamtramck, when old Martha Evancek hires him to look for her missing grandson. But even before Walker gets a chance to investigate, he's presented with a second case: an eminent Russian novelist who fears that someone is out to kill him. Walker knows the two cases are connected, but finding that link might cost him his life.
