The Mark of Cain

A funny thing about Carolyn Wells — one of many funny things about Carolyn Wells — is that, brilliant as her detectives are, their assistants are smarter. Fleming Stone and Pennington Wise may make clever deductions, but it’s always Fibsy and Zizi with the big breakthroughs — and Stone and Wise with most of the credit. And yet there’s so much trust between Penny Wise and Zizi, and between Stone and Fibsy, that I’m not mad about it. The Mark of Cain is Fibsy’s origin story, something I never thought to want, but am happy to have. And while Fibsy deserves much of the credit in this one, too, I’ve never been so happy to see Fleming Stone.
