If anyone is doing this quest there's a book locked down on a table on the shop porch with runes for both lieutenants and the first 4 locations (location 1 is marked on marble isle, you'll have to run from there - closer than running from papua) And for anyone thinking 'what the hell is Ricardo's treasures?'. Ricardo is in Yew prison, each day his ramblings include a clue to the location of the next book. Avery is in the Cat's Lair. You need to speak to him to begin the quest. Use the key words 'Ricardo', 'Treasure' 'Hidden'. This gives you the starting point. Go to the warehouse mentioned in the 'hidden' clue and double click the grey chest there - get a lantern. The lantern works like the housing quest lantern. If it's lit when you get to the day's location you'll see a book. Read the book and report back to either Lt. Dan in Serps Hold or Lt Crag in Cove. Dan is good, Crag is evil. Choose your alignment. Rewards from the chest they have. Do not do the days out of sequence.
