Case file LinkedIn Crossclimb #897: 4-letter ladder, 5 middle exhibits, combo prompt "A hyphenated word describing a golf course that's half as long as usual.". Endpoints: NINE (top) and HOLE (bottom).
Middle phase answers: "Pleasant, or the name of a city in France" = NICE; "Computer peripherals used for clicking" = MICE; "Medieval club, often with spiky bits" = MACE; "Like a bull or ram, but not a cow or ewe" = MALE; "Critter that digs tunnels" = MOLE.
Ordering phase: the valid middle chain is NICE → MICE → MACE → MALE → MOLE. This permutation is the only valid one-letter chain for these answers.
Evidence link: NINE → NICE. N→C at the third letter (NINE → NICE).
Evidence link: NICE → MICE. N→M at the first letter (NICE → MICE).
Evidence link: MICE → MACE. I→A at the second letter (MICE → MACE).
Evidence link: MACE → MALE. C→L at the third letter (MACE → MALE).
Evidence link: MALE → MOLE. A→O at the second letter (MALE → MOLE).
Evidence link: MOLE → HOLE. M→H at the first letter (MOLE → HOLE).
Verdict: NINE → NICE → MICE → MACE → MALE → MOLE → HOLE satisfies every one-letter constraint. The combo clue "A hyphenated word describing a golf course that's half as long as usual." describes both end words together — "NINE" and "HOLE" each differ by one letter from their adjacent middle rungs and satisfy the shared top+bottom prompt.
