Climbed 5 pitches of Grooved Arete to get to this, then set off round the right-hand side of the arete up to a flake for Kirkus's route. Up from the flake looked rough and mossy with no wear so went directly left round the arete through an over-hang.
Found myself in a bottomless v groove, right hand pulling out under a rough canine, right foot on a delicate incut, left foot stuffed into the rubbish v groove ending in fresh air, left hand probing round a corner for positive but inadequate finger pulls. My last gear was before I'd come round and I wasted valuable calories trying in vain to get something in above me to no avail, dropping the biner with nuts 1-6 in a fit of feeble pawing. I did not fancy falling here as the rock was very rough and the arete under the overhang very sharp. I spent a long time here trying all lack of options and just before I became totally spangled managed to reach sanctuary.
Attempted to regain the arete above but needed a rest so traversed over to the belay on The Haven on Grooved Arete. Decided against bringing Jenny up where I'd come so pulled the ropes through one at a time and chucked them back down free of the gear.
Bailed on the hollow slab above and took the offer of a top-rope from my new friend Trevor, who we just met on the Haven.
