I felt uncomfortable seeing this.  Let me see if I can explain why.   
Isn't the use of monads here unnecessary and obscure?   The use of  
inits, tails and maximumBy ground the function to a list  
representation.  There seems no hope of generalizing it to other  
monads.  The use of >>= is just an obscure way of saying (flip  
concatMap).
