Whispered Secret
A loop through Coil 2 of the Labyrinth of Tigers provides 100 secrets per action when using "The Thing in the Mirror". In Coil 1 of the Labyrinth of Tigers, you can turn your excess Jade into Secrets with "Bartering with the Tiger Keeper": 1000 => 1100. If you still have access to the Court, 'attend court functions' under "Attend to matters of romance" grants 85 plus more Connected: Society. Hunters Keep can provide 116 per action when you "Talk to Lucy"/'Ask her to take a stroll with you'. "Discuss these Extraordinary Implications with the Custodial Chef" on Mutton Island to break 4 Extraordinary Implications down into 1000 Secrets.

Cryptic Clue
For A Person of Some Importance, the Riding your Velocipede card provides 70, but is rare. If you still have access to the University, you have a good option (varies depending on where you are up to in the story). You may be able to trade in Connected: Great Game for them at the Wolfstack Docks. Otherwise 'Grimoires and almanacks' or 'Set up your own fortune-telling business' in "Steal from the gullible" or 'Fleece a fortune-teller' in "Make some money on the side" are solid options in the Flit: the total rewards of these options add to 109 pennies of goods, although only half of this is in Clues. If you have access to the 4th Coil of the Labyrinth of Tigers (unlocked with Dangerous 110) then "Scout out the Fourth Coil" is good, although it immediately relocks if you continue into the Coil. Hunters Keep provides 60 per action when you "Look more closely at the well"/'Investigate'. Should you be reduced to using an option that only provides 50 Cryptic Clues, then "Arthur's pond" in the Labyrinth of Tigers will at least increase your "time passing…" quality. Also, the "Steal ideas from other theatres - Variety is the spice of life" option at Mahogany hall also raises Tales of Mahogany hall.
