Note: a number of cells are not covered by cages. It still has just one solution.

My apologies for posting so quickly after a couple of other, non-Assassin puzzles. I'll cut mine back to one a month so I can try some others'.

Assassin 389
I found this quite hard first time through and it resisted to the very end. Found a bit of a shortcut in an optimised solution but still quite long which has become the norm for a decent, juicy Assassin. Like it! It gets a 1.60. JSudoku has a hard time.
