author
Best known for the early 20th-century adventure tale Copper Coleson’s Ghost, this elusive writer left behind a small, intriguing trail of fiction and later religious writing. What survives suggests a versatile author who moved between boys' adventure storytelling and more personal, reflective work.

by Edward P. Hendrick
Very little firmly documented biographical information about Edward P. Hendrick was available in the sources I could confirm. He is credited by Project Gutenberg as the author of Copper Coleson’s Ghost, a youthful mystery-adventure novel that helped preserve his name for modern readers.
Other surviving traces suggest he also wrote short fiction for The Youth's Companion, including a piece titled Jimmy’s Job. Book-trade listings also connect him with a later work, The Soliloquy of a Skeptic (1944), which appears to have been published in Newtonville, Massachusetts.
Because reliable biographical records are scarce, Hendrick remains something of a shadowy figure. That mystery adds a certain charm: his work survives more clearly than his life, inviting readers to discover the kind of storytelling that once entertained magazine readers and young adventure fans alike.
