The following texts and Web sites were invaluable in the writing of this novel: The Mole People: Life in the Tunnels Beneath New York City (Chicago Review Press) by Jennifer Toth; The Tunnel: The Underground Homeless of New York City (Yale University Press) by Margaret Morton; The Making of New York (www.nysl.nysed.gov); The New York Geneological and Biological Society (www.nygbs.org); Forgotten New York (www.forgotten-ny.com); and Ectopic Pregnancy Trust (www.ectopic.org).
Special thanks to Larry Labriola, New York City Police Department Narcotics Detective (ret.) for his patient answers to my million questions on NYPD policy and procedures and to Dr. Thomas Walter M.D., F.A.C.O.G., for his invaluable insights on ectopic pregnancy.
However, in spite of my careful research, I’m sure I’ve gotten something wrong along the way and I know I’ve taken artistic license as the narrative dictates. Either way, don’t blame my sources! All mistakes, intentional or otherwise, are mine.
