Richard Walker (Letters, 22 June) argues that all of your cryptic crosswords should be brought down to the level of the least difficult – on the principle of “for the many, not the few”. But that rallying cry does not mean levelling down, it means respecting and accommodating different levels and different needs, with pathways between them: the comprehensive system, not the grammar. The Guardian crossword setup is a fine instance of that principle in action, with every setter identified, and a range of difficulties from – in this typical week – the entry-level Rufus on Monday to Screw and Arachne. Please keep it that way.

• Before I retired in 2011 I used to complete the Guardian cryptic crossword every day, despite being in a busy working environment. Now work free, I have twice this week thrown down the puzzle in frustration. What has happened? Has some sadistic virus permeated your bunch of setters. Oh, and by the way, I am an ex-Mensan with a 150 IQ.
