I'm with Drxx and Muraria, in that the line should go through the letters in name order. The mention of "manipulating the grid" suggests we have to invert it to get the correct depiction, though if this has any thematic significance it escapes me. I suppose the initial depiction is pre-thematic treatment, but the preamble says it should be the work itself. There is a similar work with the title as portrayed, but the character has nothing to do with it and it doesn't fit the description from the extra letters.
It took me ages to make a name from the clashes, and I wasted a lot of time getting search results for nonentities on social media. It would have helped if the right letter choices led to real words down and across. I far preferred this week's Listener.
