A line from Liza Marklund

She paused in front of a shop
window showing a selection
of candle holders & candela-
bra that cast shadows on each 

other. It made her feel like she
was in an Escher drawing. A
man with bleached hair came
up beside her & said that "the 

mirror image is likely to be some-
thing other than the subject that 
is reflected. It might be a curve 
on the Epstein surface or polygons 

colliding on a staircase. Depends 
on the distribution of monomers 
in a coating of grafted & adsorbing 
polymers. Prepare to be amazed." 

His words, & that Escher effect, kept
her company all the way home. 
Sparks in the brain that did not
end until she shrugged off her coat.
