Hi David,
  I am a big US fan here, read almost all of your standalones.  I've tried to get hold of Semana Santa to no avail, glad you are re-issuing/re-inventing  it.    
  I loved Dante's Numbers, read it in a day, made me rent the Hitchcock film the next day. 
 I cannot wait for the next book.   One question though, why are there two titles for the new book?
Thanks, Brian
