In NH  game I  sold a  4yo for  about £55000 2 days  before  season  ended with  no  race  entries. At  end of season  it  appears as  dead, poor  thing 

 .
Do some AI  trainers  kill  horses  to get  better  replacements?
Also  at  end of  season  I noticed  a  couple of  geldings  retired  with E behind  Retired, not  sure  what  that  means.
Next  weird  thing, I  had  a  horse  that  sulks if  not in  front, it  had  won 3  times  CDG so in  its next  race I  told  jockey  to make  the pace but  he held it  up last in  a  slow  run  race. He no longer  rides  my  horses.
