"The Psychology of Interrogations and Confessions" (2003) states that some of the phraseology of the confession seemed more in line with language a police officer might use, rather than that used by an illiterate man as Evans was. Evans was kept in solitary confinement for two days before being handed over to the London police. He did not know what was happening other than his wife's body had not been found in the drain as expected. At Notting Hill police station, he was shown his wife's and daughter's clothing, and the ligature which had been used to strangle his daughter. This book cites Kennedy as a source for the conclusion that Evans felt tremendous guilt over not doing more to prevent the deaths of his wife and daughter, and particularly that his daughter's murder must have been a tremendous shock.
