Tante Lisa's stories are such a hidden gem! I stumbled upon them while digging through obscure manga forums last year. The quirky, slice-of-life vibe reminds me of 'Yotsuba&!' but with a darker twist. You can find fan translations on sites like MangaDex or Batoto—just search for the Japanese title '探偵リサ' (Tantei Lisa). Some aggregators might have it under 'Detective Lisa' too.
Word of caution though: the official English release is still spotty, so fan scans are your best bet for now. I love how the artist plays with shadows in crime scenes; it gives this eerie yet cozy feeling, like sipping cocoa while watching a noir film. The fan groups 'Baked Scans' and 'Riceballicious' did a great job preserving its charm.
