MUM TO MUM.. PLEASE TELL

HEARTBROKEN Kate McCann is pleading with the widow of a dead paedophile to break her silence in the hunt for snatched daughter Madeleine.
But Mariana Schmuecker ' herself a mother of six -has snubbed FOUR requests to reveal secrets about her husband, convicted child rapist Raymond Hewlett

Detectives believe what she knows could hold the vital key to their investigation
When the News of the World confronted her the callous German just snarled: 'Clear off! I'm sick to death of hearing about Maddie McCann!'

FLAWED

Madeleine's parents Kate and Gerry desperately want Mariana to shed light on Hewlett's links with child-sex perverts in Portugal's Algarve, where three-year-old Maddie vanished in May 2007.

Ex-fairground worker Hewlett bore a striking resemblence to the straggly-haired man seen lurking near the McCann' holiday apartment.

His previous conviction included the rape of a 12-year-old girl he lured into his car then drugged with paint stripper. And he was bragged how gipsies had offered him 'good money' for his own blonde-haired daughter aged two.

But Mariana, who suddenly shipped off to Morocco with Hewlett just three weeks after Maddie's disappearance, has stayed tight- lipped ' even about her partner's flawed alibi.

Hewlett claimed that on the Thursday Madeleine (right) was abducted he was with his family at a market up the coast in Fuzets. But that market is only held on Saturdays. A source close to the McCanns told us: 'Through detectives Kate has begged Mariana to speak out and hopes she will do the right thing. As a mother herself you'd think she'd want to help.'

Mariana lives with her kids in the German city of Aachen, in the same flat she shared with Hewlett before he died two years ago of throat cancer at 64.

A source close to the investigation said: 'Our detectives are pretty certain Mariana knows a lot about Hewlett's background and activities. That would open up doors to paedophile networks in the Algarve.
'We were never able to rule Hewlett out as a suspect. He'd have had useful information and we're convinced Mariana is more than able to fill in the gaps. But she just tells us to go away or puts the phone down.'

'We want to know WHO she knows, and WHAT she's heard about possible routes to spirit a child out of the country.'
'She and Hewlett left Portugal at a rate of knots because he feared being associated with Madeleine's disappearance.'

'We wanted to know about the six children Mariana and Hewlett had because none of them had any official birth documents. And there was a seventh child who died in mysterious circumstances.'

'They never explained how they could move from country to country with the children despite having no passports.'
