Fruit Juice

 Sugar

 Alcohol
 
 Kerosene
 
 Yeast
 
 What did all this mean? Rhyme wondered. There were too many clues. He couldn't see any relationships among them. Was the sugar from the fruit juice or from a separate location the boy had been to? Had he bought the kerosene or had he just happened to hide in a gas station or barn where the owner stored it? Alcohol was found in more than three thousand common household and industrial products--from solvents to aftershave. The yeast had undoubtedly been picked up in the gristmill, where grain had been ground into flour.
 
 After a few minutes Lincoln Rhyme's eyes flicked to another chart.

 Something that Sachs had mentioned when she was searching the boy's room came back to him.
 
 "Ben, could you open that notebook there, Garrett's notebook? I want to look at it again."
 
 "You want me to put it in the turning frame?"
 
 "No, just thumb through it," Rhyme told him.
 
 The boy's stilted drawings of the insects flipped past: a water boatman, a diving bell spider, a water strider.
 
 He remembered that Sachs had told him that, except for the wasp jar--Garrett's safe--the insects in his collection were in jars containing water. "They're all aquatic."
 
 Ben nodded. "Seem to be."
