Fire crews were called to Trades Lane at about 4.30am on Friday after a Nissan Micra went up in flames.
The Trades Lane blaze.
The blaze, which is being treated as suspicious, then spread to a Subaru parked next to it. Both cars were destroyed.
An orange KTM motorcycle was also set on fire in neighbouring Allan Lane.
Both incidents have been confirmed as deliberate by the Scottish Fire And Rescue Service, and Police Scotland said they “strongly believe” the incidents are linked.
At about 5:30am a black Mazda car was also set ablaze on Bellfield Street.
A Police Scotland spokesman said this may be linked to the earlier fires.
