Mr. Chameleon - The Case of the Blood-Stained Dollar Bills

Hubert VanDyke has found dead in his apartment. Mr. Chameleon and Detective Sergeant Dave Arnold are investigating. Dave says "He has been dead for several hours, shot between 1:00 and 2:00 AM, but one heard the shot. The other tenants are away for the weekend". Mr. Chameleon says "could it be that Silvia Southerland is in town?" Dave replies "do you think she was involved?" Chameleon says "I am almost positive. She has been constantly seen with VanDyke recently. She was seen with Archie Clyde six months ago, and he was found murdered". Dave says "Her chauffeur was found shot to death on the waterfront just last week". Chameleon says "when Archie and her chauffeur were found, they were each holding a one dollar bill in their hand. Look at what is sticking out of VanDyke's vest pocket, a blood-stained one dollar bill".
