It’s between too long between Gold posts; thankfully this week’s had plenty of pearlers:
13 across: Crow falsely in leas, lacking trouble! (3, 4)
A ridiculously good &lit, even if the in is superfluous: crow falsely – leas trouble = cry wolf = crow falsely in leads, lacking trouble.
3 down: Spiritual mentor injected heroin, perhaps, at league club? (9)
TOSH for injected heroin = shot up was genius.
1 across: My job becomes monstrous when changing hands (5)
Changing hands is a classic DA manoeuvre, and this is another classic clue: monstrous when changing hands = cruel changing hands = cluer = my job.
29 across: French connection absorbs fraud in Africa (5)
An excellent reference to a common French word: French connection absorbs fraud = et absorbs gyp = Egypt = in Africa.
25 across: Gear in Top Gear broadcast, as kids claim (7)
An excellent piece of slang and definition: broadcast as kids claim = air bags = airbags = gear in Top Gear.
24 down: Old girl hides key on island (5)
Classic piece of DA subterfuge: old girl hides key = ma hides alt = Malta = island.
