People have been gripped by a thrilling mystery as an anonymous riddler has been hiding cash all over a city.
Locals have taken to the streets to follow cryptic clues in the hopes of finding the money hidden in secret spots all over the vast metropolis of Miramichi in Canada.
The clues, which are posted on the Facebook group Miramichi Mystery Machine, have taken residents to places like forests and fields while they search for $100 (£60) and $50 (£30) bills.
No one knows who is behind the game, but that hasn’t stopped people from being captivated by it.
The mystery started earlier this month, with a single clue being posted to the Facebook page: “May 1, 7pm, $100 hidden at Ritchie Wharf."

Dozens of people turned up at the wharf and the money was found within hours.
Since then, hundreds of people have been taking part, with new clues being posted each day.
The clues have grown more puzzling and often involve voice-distorted videos or pictures of scenes from famous horror films.
The person behind the game goes by the name of Roman Dungarvan.
On his Facebook page, he states he is making amends for his family's haunting past, a reference to a ghost story about an alleged 19th-century murder on New Brunswick's Dungarvon River.
The legend revolves around a cook who is murdered and robbed of his money belt while working at a lumber camp.
Roman’s profile picture shows a figure in a black hoodie with his face hidden.
He often urges people to be careful, reminding them the money is never hidden near broken glass or in bins.
He also warns participants to be respectful of private property.
The secretive game master creates posts to suggest they are watching the search, such as "Checkered shirt. U are not close at all."
Many people don’t seem to mind not knowing who is in control of the hunt.
Tim Sutton has been taking part since the beginning and said it has created a buzz among Miramichi's residents.
He told CBC News: “Since this began I've made many new friends and also old friends whom I haven't seen in a long time.
"I am thankful they got people out of the house and active.”
Amanda Rolph and her husband, Dave, have also been taking part.
They were sceptical of the game at first but started taking part once players began posting pictures of their wins.
On day three, they found the jackpot.
Amanda said: "Everybody knew we had found it because there was a loud roar.
"It sort of ties together social media and being active, getting people outside and socialising. I think it's absolutely wonderful what they've done."
