This forms part of a series of diamond mysteries; we have now also published a Y3/4 version, and soon there will be a Y1/2 version (all leading to the same solution so anyone can join in at an appropriate level). Further updates are planned as well, to allow different outcomes. Weeks of work and testing has gone into this – we really hope you love it as much as we do!
