The Soaked Notebook

Medium — logic-grid deduction puzzle

A coach's rain-soaked notebook still holds what is left of the notes on the match's four corners.

It rained from kickoff to the final whistle in the match between the side in white and the side in black. The side in white won only four corners in the whole game, and Horacio, Ingram, Valentin and Silvestre took one each. Their coach wrote every one down in a little notebook: the minute, how the ball was sent in, and what happened next. The corners came at minutes 9, 27, 53 and 76. Each one was sent in a different way and ended a different way. Two of them, the inswinger and the outswinger, were moves the team had practised all week. The short and the driven were made up on the spot. So the times could be checked later, the coach also added some of the minutes together in pairs and jotted the totals in the margin. By the end of the match the rain had soaked the pages, and only bits of the notes could still be read.

Clues

1. A note in the margin said that the minute of the corner that ended in a goal and the minute of the one that ended in a clearance added up to 36.
2. The driven corner was taken later than the short one but earlier than the outswinger.
3. Only one of the two practised corners, the inswinger and the outswinger, ended in a goal.
4. Both Horacio and Silvestre took their corners after Ingram had taken his.
5. Either Horacio took his corner at minute 9, or he took it at minute 27.
6. Only one of these was true: Ingram's corner ended in a clearance, or the driven corner ended in a goal.
7. Either the outswinger ended in a keeper's catch, or Horacio took his corner at minute 76, but not both.
8. Valentin's corner came after Silvestre's.
