Charles Warren Adams (1833–1903) was an English lawyer, publisher and anti-vivisectionist, now known from documentary evidence to have been the author of The Notting Hill Mystery.
[2] As a lawyer Adams became involved in bailing out the once famous London publishing firm of Saunders, Otley & Co. after the two proprietors had died.
The effort was unsuccessful and liquidation ensued in 1869, but in the meantime the firm had published at least two works of Adams's own, written under the pseudonym Charles Felix.
One was a crime novel entitled Velvet Lawn (1864), and the other The Notting Hill Mystery (1865 in book form), which is thought to have been the first detective story of novel length.
The Notting Hill Mystery had already appeared as a serial in Once A Week in 1862–1863, illustrated by George du Maurier (1834–1896), author of Trilby.
