It is I, Nemo. (With a nod to 'Allo, 'Allo).
My apologies for not responding earlier, but a spell of good weather prompted SWMBO to produce a seemingly endless list of things for me to do in the garden. It seems to consist largely of some kind of chain reaction where the introduction of one new plant results in an urgent requirement to move about eight other plants into each other's location. I just do what I am told as experience has proved that resistance is fruitless.
Thank you, rossim and brendan for your kind remarks about my clue. I must admit that I was quite pleased with it but I am delighted that two such talented players should record their appreciation.
In terms of relative merit, assessment is in the gift of the individual: hence there will usually be a range of votes in Peer Review. For Clueless, the rules are quite clear: the setter chooses and we don't argue with the umpire. Parliament please note.
Notwithstanding, I now start the week with a cheerful disposition, so thanks to you both for that. It will sustain me while I toil at my manual (and, indeed, pedal) al fresco horticultural labours.
