Commander Mansfield Cummings, founding father of the Secret Service, has at last received his Blue Plaque. It was unveiled Monday 30 March, with your correspondent in attendance, not, as I had anticipated at the site of the Cummings’ 1923 death – corner of Melbury Road and Addison Road, W14 – but the site of the first proper SIS office and workshop on top of the National Liberal Office, aka Horse Guards Hotel.

I’m standing in the bathroom on the upper floor – you really don’t have to know what I’m doing –looking wistfully through the chartreuse-coloured cascade that is the weeping willow at the bottom of our garden and across the canal to Victoria Park. It is `just spring when the world is puddle-wonderful’ as American poet E.E. Cummings once put it, and we can no longer enter it. Like pints after work and an evening at the theatre, our beloved park is just a memory. It’s encaged by tall iron gates.
