Complete story — includes the ending
Retired FBI agent Robert Underhill is killed. He was investigating the old, unsolved case of Mina Davenport. Mina was kidnapped at age eight and escaped her captor 14 months prior after 10 years in captivity and returned to her wealthy parents, Nancy and Richard Davenport. However, the woman claiming to be Mina is an impostor. The impostor claims that Richard killed Mina, and wants to gain control of Mina's trust fund. Later, Underhill's blood is found on a pedal in Mina's car. Richard confesses to Underhill's murder, but is shielding "Mina". However, the DNA test proves that Mina is the Davenports' daughter. The faker had found the real Mina, attacked her and cut off some of Mina's hair. When the impostor staged her "escape" from her imaginary kidnapper, she locked herself in a gas station restroom, then shaved off all her hair and planted Mina's for the police to find. The real Mina is found and reunited with Nancy. Meanwhile, Joan's stepfather Henry Watson writes a novel whose main characters are based on her and Sherlock.
