In New York City, three intriguing, smart, and stylish private investigators open Holmes, Marple & Poe Investigations. Who are these detectives with famous names and mysterious, untraceable pasts? Brendan Holmes - A keen, science-minded sleuth with an even keener sense of smell. Margaret Marple - A charming snoop who works best undercover. Auguste Poe - A weapons expert with a weakness for muscle cars and beautiful women. The agency's daring methodology and headline-making solves attract the attention of NYPD Detective Helene Grey. Her solo investigation into her three unknowable competitors rivals the best mysteries of Sir Arthur Conan-Doyle, Agatha Christie, and Edgar Allan Poe.
