Sorry new to this - first posting on CS. Need help with13a please 'Daughter shifting mahogany retro blocks slower on landing' (13). Am convinced 'shifting' is anagrind and definition is 'slower on landing'. Am I hot or cold please? Any hints appreciated. I have 1st, 8th, 13th, letters and was going to show in post as X??????Y????Z but unsure whether this constitutes a spoiler?
