Trinity professor and Joycean scholar Kevin Coyle was one of Dublin''s most colorful -- and controversial -- characters, until someone stabbed him through the heart on Bloomsday, the annual citywide celebration honoring Ireland''s most beloved literary light. The poetic irony is not lost on Chief Superintendent Peter McGarr: one of the foremost experts on the works of James Joyce was slain on the so-called "Murderers'' Ground" made famous in the author''s magnum opus Ulysses. But the connection does not end there. And the deeper the intrepid McGarr digs, the more startling truths he uncovers about a victim''s dark, licentious history, a list of suspects as vast and varied as the characters in a great novel ... and a motive for murder that can hide as easily in the pages of a classic book as in the twisted passions of a human heart.
