Your discovery.
Their missing connection.
Try this short deduction from case 1. Ava, Ben and Cora each deliver one postcard to Elm, Quay or Hill. Each destination is used once. Read a notebook each, then compare your discoveries.
Notebook A
Ben’s card did not go to Hill. Ben’s card did not go to Quay.
Where did Ben’s card go?
Notebook B
The Orchard card did not go to Hill or Quay.
Where did Orchard go?
Who delivered Orchard? Reveal the answer
Ben delivered Orchard. Ben’s destination must be Elm. Orchard also went to Elm. Because each destination is used once, they belong together.
This is a short excerpt, not the complete case. The free sample includes every clue and the explained answer for three full cases; the paperback contains thirty.
Both pages stay visible. Sit side by side, help one another whenever you like, and swap notebooks between cases. A solo reader can use both notebooks.
THREE COMPLETE CASES TO TRY
A postcard mix-up.
A clock collection.
Five museum cabinets.
Begin with three people and a mixed-up delivery list. Next, untangle collection times. Then work out the order of five museum displays.
The 19-page sample contains the worked introduction and cases 1, 8 and 26 from the paperback. Each case includes both notebooks, optional hints and its full explained answer.
