Identical by Scott Turow

An interesting murder mystery involving identical twins and uncertain paternity and Greek-American culture. Do identical twins have the same DNA and the same fingerprints? Now the answer is no.

*Spoiler alert*
The story, it turns out, is loosely based on the myth of the Gemini, one immortal and one mortal, who, when one was dying, asked to share mortality and each spent half the time in Hades and half on Mount Olympus.
