The killer arrives at Rhyme's house and kills both Thelma and police Captain Howard Cheney. The killer is revealed to be Richard Thompson, the medical technician in charge of Rhyme's medical equipment. Richard’s real name is Marcus Andrews, a former forensics expert, who was convicted after Rhyme wrote an article accusing him of planting evidence resulting in the wrongful imprisonment of six innocent people, one of whom hanged himself. Blaming Rhyme for his imprisonment and the abuse he endured during his incarceration, he attempts to kill Rhyme out of revenge. Rhyme retaliates by crushing Marcus’ hand in his medical bed, resulting in a struggle between the two that forces them both onto the floor. Unable to move, Rhyme is almost killed by Marcus until Amelia arrives and shoots Marcus dead.
