Apparently near relations could have someone committed for madness simply by filling out a few forms.

"This is where Lord Harcourt sent poor Marguerite," I said as we entered the vast, empty entrance hall. "And all because she was sad over her baby's death."

Harcourt knew about this place after having his wife committed a few years ago.
