My second attempt at a killer sudoku puzzle, inspired by secrets I've learned watching Cracking the Cryptic.
Normal sudoku rules apply - place the digits 1 to 9 in each row, column and 3x3 box without repeating any digits.
The digits in killer cages must sum to the total in the top left corner of the cage. Digits may not repeat in a cage.
The digits on an arrow sum to the value in the circle.
Digits in shaded circles are odd.
