A book read in the 1970s – then in paperback – set in New York City about 1870 – on the upper East Side, perhaps 58th Street, near Bloomingdale’s Department Store. The first chapter opens with a crime committed on the block. It might have been winter time – not sure. It might have been a murder or it might have been some other type of crime on a person. Chapter two describes a similar crime. Same block. But 100 years later – now in the present period. Thereafter each chapter alternates the time periods – 100 years earlier, then the current period. Subsequent action took place on or around the same city block in New York. The “aha” moment came close to the end of the book when the connection was made between the two time periods. The word “Red” may have been part of the title but Google and other searches on “Red” and time warp or time shift or time travel have not revealed the title.
