Setter’s notes
4 Down is the happiest I’ve been with one of my clues in quite some time.
Across
- 1 & 3 Down An anagram (“trembled”) of HIS LEG, with “you”, once = THOU, entering — LIGHTHOUSE.
- 5 Half of “look online” = GOO(GLE) — GOO, “filth”.
- 6 Sounds like (“to be heard”) “with permission” = ALLOWED — ALOUD. The whole clue is part of the definition (semi-&lit).
- 7 “Really” = SO + “American” = US + “one” = A — SOUSA, the composer.
- 8 “Digger” = TROWEL, with “run” = R running away — TOWEL.
Down
- 1 An anagram (“surprisingly”) of STALE — LEAST.
- 2 The outside of “InstallinG” = IG + “toilet” = LOO — IGLOO.
- 4 “Boy” = LAD + IT, going up (reversed) — TIDAL: going in and out.
