Hi Claire. 13a is PSST by taking the PS from Whoops! and the ST of Stop. 17a is AXE - A + EX backwards. Now I need some assistance please as I am not very happy with the two answers I have because, if they are correct, the clues are very tenuous. For 5a, Frustrate tot, I have SCOTCH and for 6d, Pretence of many a worker, I have CANT. It\'s these two answers which are bothering me. Does anyone have the same answers? Regards, Caravaggio.
