Just Call Me Angel of the Mourning

According to this post, The Doom of the Haunted Opera contains a “weeping angel.” At first we wondered if this was a type of the statues Lewis sees in the cemetery.  You may recall in The House with a Clock in its Walls, Lewis sees gravestones with “weeping women leaning on urns and cupids extinguishing flames [64]”.

Apparently that snake-woman statue-thing following Lewis and Rose Rita around - but who can only move when they don’t look at it - is similar to a “weeping angel” in the Doctor Who universe. The creatures first appeared on television in 2007, meaning Doom predates the program by 12 years.
