Career
Further books nominally in the Mission Seeton series were then produced by two other writers using pseudonyms with "The Human Context" initials. Roy Peter Martin as "Hampton Charles" wrote three novels, which were all released in 1990. Sarah J. Mason, writing as "Hamilton Crane", then took up the series writing 14 books in all, some of which are still in print.
Mason"s books modify Carvic"s characters so much that only the names will be recognisable to readers of the first five books
