Who today remembers Leon Lewis (1833 - 1920)? A prolific Dime Novel author in the 1860's and 1870's, he penned novels as The Silver Ship, The Web Of Fate, The Reef Spider and many others, serialized in publications as The New York Weekly and New York Ledger.
While researching something else I found this advert for his novel The Water Wolf: or The Demon Of The Bermudas, published in an 1866 New York state newspaper, the Roman Citizen. The advert also provides some insight into the plotlines and characters in Lewis' story and makes for some interesting reading.
To appreciate this form of literature since long gone, spend some time at Albert Johannsen's site The House of Beadle & Adams and its Dime and Nickel Novels, the story of a vanished literature.
