Biography
"Isabel Egenton Ostrander (1883–1924) was a prolific mystery writer of the early twentieth century who used, besides her own name, the pseudonyms Robert Orr Chipperfield, David Fox, and Douglas Grant. Christopher B. Booth is sometimes (falsely) credited as a pseudonym of hers. She was born in New York City to Thomas E Ostrander and Harriet Elizabeth Bradbrook. Her Ostrander pedigree goes back to seventeenth century Kingston, New York. In the 1920s, Ostrander was notable enough that Agatha Christie parodied her in her Tommy and Tuppence anthology, *Partners in Crime* (short story collection)." - Wikipedia
