Service Clarence (1939-1945) was one of the most successful MI6 networks in Belgium during WWII.

It was led by Hector Demarque and Walthère Dewé.

Dewe l had earlier played a leading role in 'La Dame Blanche'. Throughout the war, 'Service Clarence' provided valuable information on a wide range of enemy activity, including coastal defenses, the effects of Allied bombing and the location of German units.

The Service Clarence network was a source of high quality and detailed intelligence on enemy troop movements, German order of battle, and Nazi secret weapons.

It was the "most successful Belgian network."

Furthermore, Claude Dansey, who controlled SIS operations in occupied Europe for most of the war, "later said that, in terms of the quality and quantity of its reports," it "occupied first place among the military intelligence networks operating in occupied Europe."

One if its members was Henri Roth, father of Leon-Henri Roth, a forced labourer at Peenemunde, who passed vital information of secret Germans' rocket development, leading to 1943 operation by the Allies.

Dewé used the experience of the Dame Blanche network to start a new network, codenamed Clarence. He was shot and killed while trying to avoid capture by the Germans in 1944.
