Wilhelm Ritter

Wilhelm Ritter was a Schattenjäger living in Schloss Ritter.

Background
He was the father of Wolfgang Ritter and Heinz Ritter. He took care of his sons in the early 20th century up to around mid-1920s. At some point after 1925, Heinz came to america, and changed his name to Harrison.

Day 1, Gabriel moves a clock from on top of a chest to a nearby chair in Rebecca Knight's attic. After fiddling with it, and its learning its secret (then turning the winding key), he opens it. Inside, he learns about Wilhelm Ritter from a photo hidden in a secret compartment. It showed Wilhelm with his sons Heinz and Wolfgang at Schloss Ritter in 1925. He also finds a letter (Clock Letter) addressed to his son Heinz, it was urgent and discussed the Schattenjägers.

The clock can be opened anywhere between Day 1 and Day 4. It must be opened by Day 4 in order to confirm Wolfgang's identity, and return a call to him. The official hintbook states it was opened on Day 1. The clock can also be opened on the chest, or moved over and opened on a nearby old parlor table.

Personality and traits
There is a sense of urgency in his handwriting and in the heavy use of a quill tip, bold strokes, and underlining.

Wilhelm is shown to wear dark or black clothing. In the original he seems to wear black priest-like shirt with a high neck collar. He parted his hair to one side. He doesn't appear to have a smile, but a determined look (perhaps even a hint of a frown).

Behind the scenes
In the Gabriel Knight: Sins of the Fathers (novel), his name is Karl Ritter.
