Very good I thought, went all too quickly. I got 5d quite early on from the wordplay although I was convinced it needed to rhyme with 4d for a while. Of course the connection here is the last word of 4d and the first of 5d. Everyman’s done this before. Didn’t know that meaning of 5a but Chambers gives it. Three hiddens!
And as we’re doing jokes…
Nelson, in his lifetime, was 5 ft tall. His statue in London is 15 ft tall. That’s ‘Horatio’ ... (wait for it) … of 3 to 1. 😄
