Someone approaches you because they know you read crime fiction.
It is a genre they have discovered they like, and they want your suggestions for 3 authors to look for.
You may find this difficult to do without being able to quiz them a bit further, but do try. I'm sure you are just bursting with suggestions. Leave a comment if you'd like to tell us what authors you suggested.
Add your suggestions to the Answer Garden below. If after you've added one, the entry box does not clear, just refresh the page. You should then be able to add a second. You'll probably have to refresh again to add the third. I'm not sure what will happen if people try to add simultaneously. Be patient :-)
DRAT: I've just discovered the tool will only let you add one a day, so you decide whether you will come back tomorrow and the day after to add more! (Maybe you could just tell us your other 2 suggestions in a comment)
