The First Frog of Spring

I thought the cats were behaving shiftily in the conservatory – they were spending far too much time peering round the washing machine…and when I went in there late in the evening, after Vlad and Boris had been locked out of it for a while I discovered – the First Frog of Spring – who had, I suppose, decided it was safe to come out. I opened the back door and it exited into the garden sensibly enough.

But I thought frogs were green. This one was – sort of – black.
