Finished a bit quicker than the last two weeks.
The link word (reach) at first I thought was one of a triple definition, but the answer I have matches only with the swimmers and the sandbank.
Reach is a stream between bends according to Chambers and not the same as my answer which can mean shallow water.
If that confuses anyone I am not surprised.
Re the small child/tick, I am not happy that the setter thinks a tick is the same as my answer, as ticks are parasitic and ****s are not. The setter may have meant tick in a short amount of time.
Back to my coffee
