The mark
A seal, kept.
A corded intaglio seal. A twisted rope ring, tied in a single knot at its base and finished with two tassels, carries five beads. Within it turns a dense guilloché rosette, and at the centre lies a clean die: one point of light above a horizon, with a thread falling into the water.
The catalogue
The novels live at the imprint's own home.
The novels, their stories and where to find them are kept at sealofthekeeper.com, the home of the imprint.
