do you know this manga?

i remember this manga where a "wolf" takes the form of who you love the most and eats them??? it starts of with a man coming to his aunt and uncles (?) house aft the death of the uncle (?) who was said to be eatne by a wolf(?)
all i know for certain was the aunt(?) was having and affair with a woman they had let live with them and the wolf like to be disguised as her because everyone loved her???
it end with (SPOILER!!) everyone being eaten

it seems like a weird one but i definitely remember reading it. it was like....in Victorian times (i think)
