Robert&Marie

Re: The recent traffic about the identities of Robert and Marie: In the Jungle Garden scene in Shadow the woman refers to the man thusly: "My husband wishes..." (p-168) However, on the penultimate page of Claw, Sev recalls them as "..the woman and her brother..." Does Sev's famous memory fail him? Did Wolfe screw up? Or, are the two passages not mutually contradictory? If not, is that a left-handed clue to their identities? Roy
