Lincoln House Fire ?

[Gene C]

I was reading Katherine Helm's book, "True Story of Mary, Wife of Lincoln" and I came across this on page 106-107.

"Mr. and Mrs. Lincoln went to a large party at the
Ridgleys leaving everything apparently secure at home
with a maid to watch the children. The party was very
delightful, but Mary grew restless and anxious, and
finally said 'Mr. Lincoln, we must go home.' (Mary
never called her husband by his first name, Abraham
or Abr'am, but always formally 'Mr. Lincoln.' I never
heard her speak to him in any other way except in talking
to her children, when she would say, 'Father said'
thus and so.) We must go home, Mr. Lincoln,' she
repeated, but he was reluctant and suggested that they
stay a while longer. She insisted, however, that she
must go and told him she would get someone to take her
home that he might stay and enjoy himself. With his
unfailing kindness, he said, 'I will take you home. We
will find everything all right and then we can come
back and enjoy the rest of the evening.' They did not
come back, however, as they found the house on fire,
the maid fast asleep, and the children's lives in danger.
Mr. Lincoln said he was glad he had a wife who could
'sniff fire a quarter of a mile away.'

I've never heard of this before, so I wrote Joe Di Cola and Dave Grimm about it.
Joe says it's not in "By Square & Compass" by Wayne Temple, and nothing in Lincoln Day By Day. Dave has never heard of it before either.

Any one ever heard of this?
