Edwin Alfred Bailey (b1867 Bethnal Green) m Mary Thurza Fairhead in 1895.
They are together in 1901 in Hornsey and he appears on the electoral roll there in 1906, but then disappears (although she claims to be 'married' in 1911 and is alone on an 1918 electoral roll).
It would be good to establish how he died to finish the puzzle.

Have you looked at the 1921 census to see if she’s widowed?
Do you have her 1930 death certificate?
I see on his m/c Edwin’s occupation is a clerk
Could this be him

a long shot - no middle name, no age given, there’s a mark in column headed single or unaccompanied by husband or wife
