Matrix crossword no. 16: "The Brainstrain Intersection".

Copyright John English 1995. This puzzle originally appeared in Matrix 116. (Matrix is the newletter of the British Science Fiction Association.)

(For those not in the know, The Scottish Convention was Intersection, the 53rd World Science Fiction Convention, which was held in Glasgow, Scotland, in August 1995. The guests of honour were Samuel R. Delany and Gerry Anderson. Now read on...)

In honour of The Scottish Convention, this issue's crossword consists of two intersecting puzzles. The perimeter of the top puzzle, when read clockwise starting from the top left corner, will spell out the titles of four works by one of Intersection's guests of honour (4 words, 19 letters; 2 words, 9 letters; 1 word, 12 letters; 1 word, 8 letters) while the perimeter of the bottom puzzle, when read clockwise starting from the top left corner will spell out the titles of four works by the other guest of honour (4 words, 16 letters; 2 words, 10 letters; 1 word, 8 letters; 2 words, 14 letters). The perimeters are otherwise unclued. Numbers appearing in the titles should be spelled out as words wherever necessary. The unchecked letters of the top puzzle's perimeter (including the two letters at the points where the two puzzles intersect) can be rearranged to spell O, BUT INTERSECTION BE THY CHEERY JOY while the unchecked letters of the bottom puzzle (also including the two letters at the points where the two puzzles intersect) can be rearranged to spell "WRITTEN HOT NOVEL, MAN!" RANTS BROTHER. Otherwise, all clues are normal.
