Description
Samuel Peabody is a wizard working for the White Council in a secretarial and record keeping capacity.

While not on the Senior Council, he was often in their company and was present at both the Council's Conclave in Summer Knight  and Molly Carpenter's warlock hearing in Proven Guilty.

Peabody compiled the book Die Lied der Erlking on Erlking lore, sometime "early last century" (presumably the 20th). He either does not speak German or is very bad at it, as he published his book Die Lied der Erlking with a grammatically incorrect title. He called German an "untidy language".

During a conversation with Ebenezar McCoy, Harry calls him a "beauracromancer" and Ebenezar says that a war can't be fought without clerks.

Turn Coat
In Turn Coat, when Donald Morgan was accused of the murder of senior council member LaFortier Dresden hid the fugitive Morgan from the Wardens. Harry goes to Headquarters to secretly get more information. While there, Harry notices Peabody flitting between Senior Council members getting their signatures for this or that like an annoying gnat. He even tried to get Harry's signature and became quite incensed when Harry refused.

In Turn Coat, at Morgan's trial, Dresden accuses Peabody of being the real murderer who framed Morgan, manipulated the younger Wardens and subtly influenced the minds of the Senior Council. Ebenezar McCoy and Carlos Ramirez searched his rooms and found that the inks he used to gain signatures contained alchemical substances that allowed Peabody to manipulate persons to do his bidding.

At the end of Turn Coat,  in order to escape, Peabody smashes an ink bottle that freed a Mistfiend laced in Mordite and using pre-implanted trigger phrase "the end is nigh" to immobilize the young Wardens as he fled. Harry gives chase though the Hidden Halls of Edinburgh. He freezes Wardens at all of the checkpoints repeating the phrase. Peabody opened a way to the Nevernever, then he overpowered Dresden and was about to kill him when Donald Morgan shot Peabody twice in the head with Anastasia Luccio's gun, killing him.
