"The Indiscretion of the Duchess,"
"The Flight of a Shadow,"
"The Secret of Narcisse," etc.,

where the more idiomatic forms,

"The Duchess's Indiscretion,"
"Narcisse's Secret,"
"A Shadow's Flight," etc.,

are certainly not euphonic.

Of the others, 8 would not be injured by a change, and no less than 30
would be improved from the standpoint of idiomatic English. It may be well
to quote these thirty titles. They are:

"The Shadow of Hilton Fernbrook,"
"The Statement of Stella Maberly,"
"The Shadow of John Wallace,"
"The Banishment of Jessop Blythe,"
"The Desire of the Moth,"
"The Island of Dr. Moreau,"
"The Damnation of Theron Ware,"
"The Courtship of Morrice Buckler,"
"The Daughter of a Stoic,"
"The Lament of Dives,"
"The Heart of Princess Osra,"
"The Death of the Lion,"
"The Vengeance of James Vansittart,"
"The Wife of a Vain Man,"
