Next spot I was into something a bit better - a bigger, darker fish that again did it's best to shed the barbless hook in the overhanging grass and needed an undignified bum-slide down the bank to land it. This one took the nymph literally as it hit the surface, so guess they must be used to the odd terrestrial dropping in.
Two more followed, including one from a section of the brook right next to a road as oblivious, early morning commuters whizzed behind me. Carried on upstream a bit further than last time and came across a nice pool on the outside of a bend, complete with rising trout! Catapulted the nymph up to the head of the pool and had it taken on the drop. Popped that one back in downstream so as not to disturb the others and went back for another shot. Next drift back down the pool the tipped jagged over as the nymph was again taken on the drop. This one buried itself in some tree roots to my left, but I managed to pop it out into the net with a bit of persuasion.
Had a few more casts, but the disturbance from the last fish had probably spooked the others as I just had one half-hearted pull. Carried on a bit further upstream, but the sun and dog walkers had come out by now. The grass pollen, which had been coming up in yellow clouds all morning and coating my waders and my jacket, was also starting to get to my throat and eyes.
Reluctantly headed back to the car and joined the rat race again.
