I remember when Queens Road Mosque was a synagogue.
Local Muslims bought it and converted it in 1981, shortly after I buried my mother in the Victorian cemetery opposite. My next door neighbour worshipped there. Then the congregation bought houses to the back and side, and extended into them. They altered the windows to look eastern and painted the buildings eau de Nile green. My Dad joined Mum in the cemetery and I got on with my life returning with flowers when I could, which was less often after I married and had a small child.
One day I turned into Queens Road and there was a huge hole in the ground. On my next visit there was a great cube of a building where a minaret that resembled a scud missile was dwarfed only by an enormous green dome. The new mosque dominated the Anglican church, the schools service art centre and the cemetery chapel. This was a new world.
Unlike the Lea Bridge Road mosque there is no obvious Women's entrance and I have never seen a woman or child on the entrance steps.
I wrote in here in 2006 when this plot came to light:- something about that missile brooding over my parent's grave upsets me everytime I visit. . . I would say to my husband, "One day something will happen, and that place will be at the centre of it." 
I never thought I would be so horribly, horribly right. I always found the waves of evil coming from that building palpable, an effect other mosques, and heaven alone knows there are enough of them in east London these days, don't have on me.
The Times now has more detail of the 20 years of extremist recruiting.
The mosque frequented by key members of the airline plot terror cell has been a recruiting ground for Islamist extremists for more than 20 years, The Times can reveal.
The Queen’s Road mosque in Walthamstow, East London, was a regular place of worship and meeting place for central figures from the group.
Abdullah Ahmed Ali, the cell leader, prayed there and met with his associates including Waheed Zaman, who lived opposite.
The mosque is currently under the control of Tablighi Jamaat, an ultraorthodox Islamic sect which preaches that Muslims should replicate the life of Muhammad and tells them it is their duty to travel the world converting non-believers to the one true faith.
world believe Tablighi Jamaat’s fundamentalism makes some of its followers easy prey for terrorist recruiters. Mohammed Sidique Khan, the leader of the London 7/7 bombers, was an adherent.
Almost without exception, the Walthamstow bombers were Tablighi followers. They sometimes went to huge Friday night gatherings in West Ham on the site beside the 2012 Olympic Park where the sect wants to build Europe's biggest mosque with space for 12,000 people to pray.
In 1989, however, before it became a Tablighi mosque, followers of the extremist preacher Omar Bakri Mohammed frequently hosted study circles at Queen’s Road.
In August that year I attended such a gathering led by Bakri Mohammed’s lieutenants, then operating under the banner of Hizb-ut-Tahrir (Party of Liberation).
The young men present told me of the evils of drink and discos, decried "free intermingling of the sexes" and preached that "God knows best because he created us". 
"Islam isn't a religion where you can only adopt part of it and only talk about that. You have to adopt the whole Islamic viewpoint on society. There can be no compromise with the divine system which has been revealed to us."The name of al-Qaeda was not known at the time, but the ideology now associated with it - the narrative of the supremacy of fundamentalist Islam - was clearly present.
Three years after the plot was foiled there remains a sense of disbelief that its foundations were laid here (in Walthamstow). But the cold facts are that the bomb factory was here, the key plotters were arrested in the car park of the Town Hall and many of those willing to be martyrs for Osama bin Laden had been taught in Walthamstow schools.
Afzal Akram, the local councillor whose brief included "community cohesion", insisted that Queen's Road mosque itself is not part of the problem.
"It's got nothing to do with the imams or the mosque - some of my friends and family pray there, I've been there myself," he says. "None of the mosques here have been used to preach extremism. Individuals may have met at particular mosques and individuals may live within a stone's throw of the mosque. But I wouldn't put two and two together."
The Queen’s Road mosque declined to comment, despite approaches made through the Muslim Council of Britain.
However, two years ago Tablighi Jamaat hired a PR firm and set up a website to publicise its Olympic plans. A statement on that site said: "We do not teach an extremist line, but we clearly can't speak for every single one of those who have ever attended our mosques - there are several thousand people at our weekly gatherings."
It added: “We utterly refute any links to terrorism or terrorists.” Mary and I attended their open day and listened quietly to what has proved to be lies.
But one community leader, who has devoted years to council politics and inter-faith work, told The Times that the Muslim community did not recognise that extremism was a problem.
"I don't want to add fuel to the fire, but the problem is within the Muslim community and its attitude to the extremists," he said. "You speak to the community elders and they smile and say, 'It's not a big problem, if we ignore them they'll go away'. That seems a dangerous attitude to me and the wrong one to take.
"They've got to do some heart-searching because at the moment they're just burying their heads in the sand".
If an earthquake were to swallow that place up I, for one, would not be sorry.
