Cambridge， Massachusetts， is home to Homer and Mary Kelly， Harvard University， the Mount Auburn Cemetery， and Leonard Sheldrake. Leonard， Homer s friend， often compares the many-faceted Cambridge to a favorite engraving， filled with strange power and wonder， by the twentieth-century Dutch artist Maurits Escher. So he is thrilled when Cambridge hosts an Escher exhibit. There， Leonard is smitten by a mysterious woman in a green coat named Frieda who is equally enthralled by the artist s brilliance. But Frieda hurries off without divulging her last name， her address， or her phone number. Despite their all-too-brief encounter， Leonard is now desperately in love with this elusive woman-and desperate to find her. Homer and Mary offer to help， but soon their search takes on the aspect of an Escher-etched labyrinth in which they will encounter past murders and present secrets， modern fortune- tellers and the graveyard ghosts of Mount Auburn. A feast of art， erudition， intrigue， and humor， The Escher Twist is a fantastic read for Jane Langton s legion of fans.
