File 972: Encounter with ripples
Cover text: Conan's memories which have been awakened along with the sound of ripples... Young Shinichi, Ran and Sera... What is the truth of that encounter in the sea which happened long ago?
10 years ago: a beach somewhere
Shuuichi, lying under a parasol, is visited by Shuukichi and Masumi. Shuuichi has had a brawl with Mary, his mother, and has a wound on one eye
Mary was supposed to do what an email her husband left behind (the wording implies the husband is dead or missing): lie low in Japan
But Shuuichi has obtained US nationality to enter the FBI and investigate the truth of the case his father stumbled upon
Masumi doesn't know any of that and wants to make Shuuichi smile: she tries to do all kind of pranks but Shuuichi doesn't react
In the end she tries stuffing french fries into his nose's nostrils and gets scolded by both Shuuichi and Mary
When Mary removes the salt below Masumi's nose she says "chips" aloud and Yuriko overhears her
Shuichi then tells Mary than when you're so famous that everyone knows you there's no safe country to be at and it's better to beat the opponent before your true colors are revealed...
... And Shinichi suddenly shows up there and says "It's so obvious! Bro, you're a clown!"
Both son and mother wonder what he's talking about and Shinichi says that Shuuichi has a mark on his left wrist and it's an accordion belt mark and that the left eye's wound is make-up remains (a mere clown doesn't cry or so he says): all of Shinichi's "deductions" are totally off the mark but Shuuichi smiles and Masumi sees that smile
Shuuichi asks him who he is and Shinichi introduces himself as well as saying he's "Holmes' apprentice": Ran comes to search for him
3 bad-looking men show up on the area: they were trying to get a free yakisoba meal at the sea-house by making up the lie that there flies on the yakisoba but Shinichi stopped them so they've got an unjustified ressenment with him
They try to beat Shinichi up but Shuuichi beats them up with his blinding sundome (a variant of karate) and drives them off: Shuukichi then asks them to play with Masumi
But then they all see how a car falls from a nearby cliff into the sea...
Side-note: "Next number: Akai and young Shinichi take on a case!"
